weber, unit of magnetic flux in the International System of Units (SI), defined as the amount of flux that, linking an electrical circuit of one turn (one loop of wire), produces in it an electromotive force of one volt as the flux is reduced to zero at a uniform rate in one second. Magnetic flux density is calculated near the poles of the magnet, where the magnetic field is highest and the region as compared to others is lowest. The weber is named for Wilhelm E. Weber ( 1804-1891 ). [9] "After consultation, the ampere was adopted as the fourth unit of the Giorgi system in Paris in 1950."[11]. Discussions of a theoretical nature were opened at which eminent electrical engineers and physicists considered whether magnetic field strength and magnetic flux density were in fact quantities of the same nature. Quantity called magnetic field strength (magnetizing force) is a measure of the applied magnetic field from external currents, independent of the material's response. The development of the electric telegraph (an invention of Gauss and Weber) demonstrated the need for accurate electrical measurements. The magnetic field at any given point is specified by both a direction and a . [3] ". Earlier systems. Our editors will review what youve submitted and determine whether to revise the article. [9], In 1930, TC1 decided that the magnetic field strength (H) is of a different nature from the magnetic flux density (B),[9] and took up the question of naming the units for these fields and related quantities, among them the integral of magnetic flux density. In the CGS system of units, a.k.a. Officially:.mw-parser-output .templatequote{overflow:hidden;margin:1em 0;padding:0 40px}.mw-parser-output .templatequote .templatequotecite{line-height:1.5em;text-align:left;padding-left:1.6em;margin-top:0}, Weber (unit of magnetic flux) The weber is the magnetic flux that, linking a circuit of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero at a uniform rate in 1 second.[3]. The Relationship between Gauss & Tesla is 1T = 10000G. The weber is commonly expressed in a multitude of other units: The weber is named after Wilhelm Eduard Weber. Omissions? This system was given the designation of "Giorgi system". Suppose that Weber and Gauss\u0026#x27;s transmission line was as diagrammed in Figure P30.18. [3][4] A complete system of metric electrical and magnetic units was proposed by Wilhelm Eduard Weber in 1851,[5] based on the idea that electrical units could be defined solely in relation to absolute units of length, mass, and time. Tesla is equal to Newton per metre ampere. Updates? It was proposed as a system of practical international units by unanimous recommendation at the International Electrical Congress (Chicago, 1893), discussed at other Congresses, and finally adopted at the International Conference on Electric Units and Standards in London in 1908. A practical-size unit of magnetic field is named for Johann Karl Friedrich Gauss. [Note 3], The SI definitions of the electrical units are formally equivalent to the 1908 international definitions, and so there should not have been any change in the size of the units. The terminology of some of the definitions has been updated to modern usage. Magnetic field is the measure of magnetic flux per unit area. That is, one maxwell is the total flux across a surface of one square centimetre perpendicular to a magnetic field of strength one gauss. What is the relationship between Weber and Tesla? This means that some results will be rounded to avoid the numbers getting too long. [17], The International Committee for Weights and Measures (CIPM) approved a new set of definitions for electrical units, based on the rationalized MKSA system, in 1946, and these were internationally adopted under the Metre Convention by the 9thGeneral Conference on Weights and Measures in 1948. The link between electromagnetic units and the more familiar units of length, mass and time was first demonstrated by Carl Friedrich Gauss in 1832 with his measurement of the Earth's magnetic field, and the principle was extended to electrical measurements by Franz Ernst Neumann in 1845. Magnetic Flux Density is the amount of magnetic flux flowing through a unit area and is perpendicular to the direction of magnetic flux. Wilhelm Weber. gauss to weber/meter (Gs, GWb/m) measurement units conversion. The Gauss ( G s or G) is the CGS unit for the measurement of magnetic field B, which is also called the magnetic flux density or the magnetic induction. Then 1 Wb = : s = 1 (Tm2) = 1 J/A. A flux density of one Weber per square meter or Wb/m2 is one Tesla, where Weber (Wb) = SI unit of Magnetic flux (number of magnetic field lines passing through a given closed surface). A = V. s = H. A = T. m 2 = J A = 10 8 M. x where, Wb = Weber T = Tesla V = volt m = metre J = joule s = second H = Henry A = ampere Mx = Maxwell Nevertheless, the international ohm and the international volt were not usually realized in absolute terms but by reference to a standard resistance and a standard electromotive force respectively. Wilhelm Weber was born on October 24, 1804, in Wittenberg, Germany. To find the flux density, divide the total flux by the total area. The weber is named after the German physicist Wilhelm Eduard Weber (18041891). The practical-size unit of magnetic field is named for Johann Karl Friedrich Gauss. Q. Weber (Wb) is the SI unit of magnetic flux. Weber number is often useful in analysing fluid flows whenever there is an interface between two different fluids, especially for fluids with multiphase flowing with strongly curved surfaces.

Weber is commonly expressed in a multitude of other units. Weber per square metre (Wb/m) 1. The 1893 system of units was overdefined, as can be seen from an examination of Ohm's law: By Ohm's law, knowing any two of the physical quantities V, I or R (potential difference, current or resistance) will define the third, and yet the 1893 system defines the units for all three quantities. [17], The choice of electrical unit for the base unit in a rationalized system depends only on practical considerations, particularly the ability to realize the unit accurately and reproducibly. The SI unit of magnetic flux is the Weber (Wb). Magnetic flux can be measured using a magnetometer, in the same way as it is used for measuring magnetic fields. There are various fields where the magnetic field is used, such as: 3. One Gauss is expressed as one Maxwell per square centimetre. "[6], The International Electrotechnical Commission began work on terminology in 1909 and established Technical Committee 1 in 1911, its oldest established committee,[7] "to sanction the terms and definitions used in the different electrotechnical fields and to determine the equivalence of the terms used in the different languages. When both wires carry the same current I, the wires repel each other so that the angle \\theta between the supporting strings is 16.0^{\\circ} . It is a vector quantity. They are endless continuous loops In the CGS system, the smallest unit of the magnetic field is Gauss. The second step is to measure the total area on which the flux is acting. set up a committee in 1861, initially to examine standards for electrical resistance,[9] which was expanded in 1862 to include other electrical standards. W b = k g. m 2 s 2. 1 maxwell 10 4 tesla (10 2 metre) 2 = 10 8 weber See also This group also recognized that any one of the practical units already in use (ohm, ampere, volt, henry, farad, coulomb, and weber), could equally serve as the fourth fundamental unit. Unit Of Magnetic Flux Unit Of Current Other Common Units Some other common unit of Magnetic Field is given below: Apart from the SI system, the B-field in the Gaussian-CGS system is measured with the unit gauss (G). To summarise the entire topic, below given is a quick revision table representing all the important concepts related to Weber. The magnetic field at any given point is specified by both a direction and a magnitude (or . Magnetic flux is the number of magnetic lines that pass through any closed surface under the influence of a magnetic field. The SI unit of magnetic flux is Weber. [citation needed], In 1935, TC 1 recommended names for several electrical units, including the weber for the practical unit of magnetic flux (and the maxwell for the CGS unit). The earths magnetic field is 1000 times less than that of a bar magnet. Line per square centimetre. Weber is the unit of magnetic flux that causes the electromotive force of one volt in a circuit of one rotation when generated/removed in one second. Magnetic Flux - (Measured in Weber) - Magnetic flux () is the number of magnetic field lines passing through a surface (such as a loop of wire). It is required to convert the unit of magnetic flux from Unit pole to Weber, in magnetic flux. Here are the possible solutions for "CGS unit of magnetic field strength equivalent to 79.58 amperes per metre" clue. 10,000. The realizations recommended in 1908 are not exactly equivalent to the absolute definitions: recommended conversion factors[22] are. Similar magnetic poles repel. Magnetic flux density is denoted by B and is related to the magnetic field denoted by H, as follows: B = H, where = magnetic permeability. had developed two sets of CGS units. (Andre Ampre suggested electrical signaling in 1821; Samuel Morse built a telegraph line between Baltimore and Washington in 1844.) [1] It was rendered obsolete by the inclusion of electromagnetic units in the International System of Units (SI) at the 9th General Conference on Weights and Measures in 1948. Electric currents and the magnetic moments of minute particles inside the object give rise to a magnetic field, which affects other currents and magnetic moments. While every effort has been made to follow citation style rules, there may be some discrepancies. According to Lorentz Force Law, F (Magnetic) = qvB, where q = electric charge, v = velocity, and B = magnetic field. unit of magnetic flux is weber. What are the Applications of the Magnetic Field? A charge q in an electric field E experiences a force F= qE. The Weber number (We) is a dimensionless number employed in the field of fluid mechanics. Magnetic flux density - (Measured in Tesla) - Magnetic Flux Density is amount of magnetic flux through unit area taken perpendicular to direction of magnetic flux. What are the Applications of Magnetic Flux? PROBLEM TO BE SOLVED: To solve such problems that a correct angle is not outputted when abnormality generates in a rotation angle measuring device using a magnetic resistance element by a bridge structure, and a function of an upper system using the rotation angle measuring device is stopped. [3] The weber is commonly expressed in a multitude of other units: where Wb = weber, = ohm, C = coulomb, V = volt, T = tesla, J = joule, It is denoted by the symbol 'B'. The earths magnetic poles move about 40 km each year. The weber is volt seconds or, in terms of base units only, The weber was introduced as a practical electromagnetic unit = 10 maxwells at the International Electrotechnical Commission in Paris in 1933, but it was not much used until the meter-kilogram-second system was generally adopted. 1 tesla = 1 weber m 2. . Determine the magnetic flux through a field that has a length of 0.50 m and a breadth of 0.60 m, where a magnetic field of 0.02 T is applied to an angle of 45, According to the given problem, the magnetic field is 0.02 T at an angle of 45, Magnetic flux is the number of magnetic lines that pass through any closed surface under the influence of a magnetic field. Complete step-by-step answer: The unit of magnetic field is Tesla. weber, unit of magnetic flux in the International System of Units (SI), defined as the amount of flux that, linking an electrical circuit of one turn (one loop of wire), produces in it an electromotive force of one volt as the flux is reduced to zero at a uniform rate in one second. 2. Both were scientists at Gttingen, Germany. The units agreed at this conference were termed "international" units, to distinguish them from their predecessors. In 1861, the British Association for the Advancement of Science (known as "The BA"[4]) established a committee under William Thomson (later Lord Kelvin) to study electrical units. [9][10], It was decided to extend the existing series of practical units into a complete comprehensive system of physical units, the recommendation being adopted in 1935 "that the system with four fundamental units proposed by Professor Giorgi be adopted subject to the fourth fundamental unit being eventually selected". The SI unit of magnetic flux is Weber and the CGS unit is Maxwell. unit pole to weber (Wb) converter is the magnetic flux converter from one unit to another. A flux density of one Wb/m 2 (one Weber per square metre) is one Tesla (T). An additional problem with the CGS system of electrical units, pointed out as early as 1882 by Oliver Heaviside,[19] was that they were not "rationalized", that is they failed to properly take account of permittivity and permeability as properties of a medium. Q. A change in flux of one weber per second will induce an electromotive force of one volt (produce an electric potential difference of one volt across two open-circuited terminals). [6][7] Weber's original proposal was based on a millimetremilligramsecond system of units. Hence, Tesla is the unit of Magnetic field. Gauss (G) 10,000. Today's crossword puzzle clue is a general knowledge one: CGS unit of magnetic field strength equivalent to 79.58 amperes per metre. The 1893 system had three base units: the international ampere, the international ohm and the international volt. This "led eventually to the universal adoption of the Giorgi system, which unified electromagnetic units with the MKS dimensional system of units, the whole now known simply as the SI system (Systme International d'units). As disagreement continued, the IEC decided on an effort to remedy the situation. A magnetic flux density of one Wb/m2 (one weber per square metre) is one tesla. These applications of magnetic flux are mainly valid in the magnetic sensor for android, navigation, industrial, and scientific measurement applications. Please refer to the appropriate style manual or other sources if you have any questions. The unit of magnetic flux is named for Wilhelm Weber. It is measured in Weber per metre square, which is equal to Tesla. In physics, the weber (/veb-, wb.r/ VAY-, WEH-br;[1][2] symbol: Wb) is the unit of magnetic flux in the International System of Units (SI), whose units are volt-second. The unit of magnetic flux is named for Wilhelm Weber.

The weber is commonly expressed in a multitude of other units: Wb = kg m 2 s 2 A = C = V . [21] Under this system, which would become the International System of Units (SI), the ohm is a derived unit. Weber (unit of magnetic flux) The Weber is the magnetic flux that, linking a circuit of one turn, would produce in it an electromotive force of 1 Volt if it were reduced to zero at a uniform rate in 1 second. Centi-Gram-Second, one Weber is equal to 108 Maxwells. The ampere rapidly gained support over the ohm, as many national standards laboratories were already realizing the ampere in absolute terms using ampere balances. At the behest of William Thomson,[8] the British Association for the Advancement of Science (B.A.) 1 tesla is equal to 1 Weber per metre square, which corresponds to 104 gausses. The weber may be defined in terms of Faraday's law, which relates a changing magnetic flux through a loop to the electric field around the loop. What do Magnetic field and Weber (unit) have in common. The international units did not have the same formal legal status as the metre and the kilogram through the Metre Convention (1875), although several countries adopted the definition within their national laws (e.g., the United States, through Public Law105 of July12, 1894[15]). The unit of magnetic flux is named for Wilhelm Weber.

CGS unit of magnetic field strength is oersted, and SI unit is ampere/meter. Two long, parallel wires, each having a mass per unit length of 40.0 \\mathrm{~g} / \\mathrm{m}, are supported in a horizontal plane by strings 6.00 \\mathrm{~cm} long. [5] In a February 1902 manuscript, with handwritten notes of Oliver Heaviside, Giovanni Giorgi proposed a set of rational units of electromagnetism including the weber, noting that "the product of the volt into the second has been called the weber by the B. Read the following statements and answer whether the given statement is true or false. The International System of Electrical and Magnetic Units is an obsolete system of units used for measuring electrical and magnetic quantities. It was named in honour of the 19th-century German physicist Wilhelm Eduard Weber and equals 108 maxwells, the unit used in the centimetregramsecond system. Like other SI units, the weber can modified by adding a prefix that multiplies it by a power of 10. Magnetisation defines the material's response- it is magnetic moment per unit volume of material. Weber's number was named after a professor of naval mechanics at the Polytechnic Institute of Berlin, named Moritz Weber (18711951). In terms of Faraday's law, the SI unit of flux is Weber, it is related to a changing magnetic flux through a loop to the electric field around the loop. Magnetism is one aspect of the combined principle of electromagnetism. Q. SI unit of Magnetic flux is weber and its CGS unit is maxwell. And dimensions of the field are given as 0.50 m and 0.60 m. Magnetism is one of the sequences of physical phenomena that are intervened by magnetic fields. It instructed a task force to study the question in readiness for the next meeting. (a) Are the currents in the same direction or in opposite directions? The strength of the magnetic field in any region is measured using a unit called Tesla, denoted by T. This unit is considered in a metre-kilogram-second system. So, the flux per unit of cross-sectional area is called flux density. weber/centimeter to weber/inch (Wb/cmWb/in) measurement units conversion. Both were scientist. With advances in the theory of electromagnetism and in quantity calculus, it became apparent that, in addition to the base units of time, length and mass, a coherent system of units could include only one electromagnetic base unit. "[12], In 1938, TC24 "recommended as a connecting link [from mechanical to electrical units] the permeability of free space with the value of 0 = 4107H/m. If we look at the conversion it is 1 T = 10000 G. Meanwhile, the H-field is measured with the help of Oersted (Oe) in the CGS system. Physics Magnetic Field Units of Magnetism: Ampere, Tesla, Weber, Henry Magnetism has many different units, such as the Ampere for electric current, Tesla for magnetic field, Weber for magnetic flux and Henry for inductance. So, the correct option is A. A practical-size unit of magnetic field is named for Johann Karl Friedrich Gauss. The SI unit of magnetic flux is Weber and the CGS unit is Maxwell. Researching magnetism with the great mathematician and astronomer Karl Friedrich Gauss in the 1830s, German physicist Wilhelm Weber developed and enhanced a variety of devices for sensitively detecting and measuring magnetic fields and electrical currents. According to the given problem, the magnetic field is 0.02 T at an angle of 45o. The magnetic field experiences a force perpendicular to its own velocity and the magnetic field. Centi-Gram-Second, one Weber is equal to 10, The Weber number (We) is a dimensionless number employed in the field of fluid mechanics. It is measured in SI base units of, When the angle between the magnetic field vector B. and the area vector A is nearly equal to or equal to 90, the resulting flux is very low or zero, respectively. With improvements in measurement techniques, it was soon recognised that, The solution came at an international conference in London in 1908. As with every SI unit named for a person, its symbol starts with an upper case letter (Wb), but when written in full it follows the rules for capitalisation of a common noun; i.e., "weber" becomes capitalised at the beginning of a sentence and in titles, but is otherwise in lower case. Important - The magnetic field intensity can also be given in terms of magnetic flux density (B) as follows, B = 0 r H H = B 0 r. ( 3) Numerical Example (1) A magnetic field is produces by a pole of strength 100 mWb placed in vacuum. Relation between SI and CGS unit of magnetic field intensity: 1 Gauss = 1 10 4 Tesla Or, 1 Tesla = 10, 000 Gauss A magnetic field is a physical field surrounding conductors with electric currents, moving electrically charged particles, magnetic materials, and time-varying electric fields. 1 unit pole is 1.256637061436E-7 weber (Wb). The chosen method was based on the resistivity of mercury, by measuring the resistance of a column of mercury of specified dimensions (106cm1mm2): however, the chosen length of column was almost 3millimetres too short, leading to a difference of 0.28% between the new practical units and the CGS units which were supposedly their basis.[14]. A. There were several other modifications of less practical importance:[1]. The eq. This is the very basic unit conversion, which you will learn in primary classes. Along with their individual accomplishments, Weber and Gauss built a telegraph in 1833 that consisted of a battery and switch, at one end of a transmission line 3 km long, operating an electromagnet at the other end. also proposed a set of "practical" or "reproduceable" units, which were not directly linked to the CGS system but which were, as near as experimental accuracy allowed, equal to multiples of the corresponding CGS units. Giorgi was also a great proponent of rationalization of the electrical units. [13], The B.A. Tesla is equal to Newton per metre ampere. Along with their individual accomplishments, Weber and Gauss built a telegraph in 1833 that consisted of a battery and switch, at one end of a transmission line 3 km long, operating an electromagnet at the other end. "[8], It was not until 1927 that TC1 dealt with the study of various outstanding problems concerning electrical and magnetic quantities and units. system of practical units gained considerable international support, and was adopted with one important modification by the First International Conference of Electricians (Paris, 1881). The maxwell is a non-SI unit. Explore more crossword clues and answers by clicking on the results or quizzes. The usual direction of the flow of magnetic flux is from the north pole to the south pole. Weber number is often useful in analysing fluid flows whenever there is an, 1. Units of Magnetism: Ampere, Tesla, Weber, Henry Go to Topic Explanations (1) Vinitha Ranganeni Text 3 Units of Magnetism The first discovery relating to the field of magnetism and magnet was by Nikola Tesla. 1 tesla is equal to 1 Weber per metre square, which corresponds to 10, CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. This is used to help to describe any area that is passed through any magnetic field. S.I. Officially: ". We will try to find the right answer to this particular crossword clue. although slightly different factors may apply for individual standards in national measurement laboratories. The practical-size unit of magnetic field is named for Johann Karl Friedrich Gauss. Let us know if you have suggestions to improve this article (requires login). However these units were both difficult to realize and (often) impractically small. About Magnetic Field Unit Converter tool. For the word puzzle clue of noun a unit of magnetic flux density in the meter kilogram second system equivalent to one weber per square meter, the Sporcle Puzzle Library found the following results. The link between electromagnetic units and the more familiar units of length, mass and time was first demonstrated by Carl Friedrich Gauss in 1832 with his measurement of the Earth's magnetic field,[2] and the principle was extended to electrical measurements by Franz Ernst Neumann in 1845. The essential point was to reduce the number of base units from three to two by redefining the international volt as a derived unit. The strength of the magnetic field in any region is measured using a unit called Tesla, denoted by T. This unit is considered in a metre-kilogram-second system. Magnetic Induction When a charged particle is moving, it experiences a force that is usually defined as the magnetic field or magnetic induction or magnetic flux intensity. The ohm is the electric resistance between two points of a conductor when a constant potential difference of 1volt, applied to these points, produces in the conductor a current of 1ampere, the conductor not being the seat of any electromotive force. The British Association had constructed an artefact representation of the ohm (a standard length of resistance wire which had a resistance of 109CGSunits of electric resistance, that is one ohm) whereas the international conference preferred a method of realization that could be repeated in different laboratories in different countries. The SI Unit of Magnetic Flux, Weber can be calculated in a variety of other units, as shown below: Wb = kg m2/s2 A = V.s = H.A = T.m2 = J/A = 108Mx Where, Wb = Weber T = Tesla V = volt m = meter J = joule s = second H = Henry A = ampere Mx = Maxwell CGS Unit of Magnetic Flux Maxwell (Mx) or Abweber is the CGS unit of magnetic flux (abWb). 1 maxwell = 1 gauss 2. The total amount of the flux produced by a magnet is important to understand how dense or concentrated the flux is, per unit of planar area. [Note 4] As the international ampere was usually realized by means of an ampere balance rather than electrolytically,[16] 1Aint= 1A. Maxwell per square centimetre (Mw/cm) 10,000. In the solar system, there are only five planets having magnetic fields, which are Earth, Jupiter, Saturn, Neptune, and Uranus. It consisted of a battery and switch that were positioned at one end of a transmission line 3 \\mathrm{~km} long and operated an electromagnet at the other end. . A magnetic field is defined as a region near a magnetic charge that is under the influence of the force of magnetism. In the CGS system of units, a.k.a.

[10] After two years of discussion, experiment and considerable differences of opinion,[8] the committee decided to adapt Weber's approach to the CGS system of units,[11] but used metre, gramme and second as their absolute units. Weber (unit of magnetic flux) The weber is the magnetic flux that, linking a circuit of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero at a uniform rate in 1 second. Its dimension is. It is the SI unit of magnetic field. The weber is the related SI unit of magnetic flux, which was defined in 1946. These poles exert action-at-a-distance forces on each other, according to the law of magnetic poles: Opposite magnetic poles attract. Hyperleap helps uncover and suggest relationships using custom algorithms. The conversion factor for the "electrolytic" ampere (Aelec) can be calculated from modern values of the atomic weight of silver and the Faraday constant: International System of Electrical and Magnetic Units. While often rounding works up to a specific decimal place, we've decided that limiting the length of the result to 13 digits would be more favorable to keep the results consistent. Gamma () [13] The B.A. 25 results for "noun . A magnetic field is a physical field surrounding conductors with electric currents, moving electrically charged particles, magnetic materials, and time-varying electric fields. (2) defines AT/m as the unit of magnetic field intensity, that equivalent to N/Wb. We use rounding at unit-conversion.info. Note: The SI unit of magnetic field is in the name of Nikola Tesla (Symbolized as T). [16][20] The International Electrotechnical Commission (IEC) adopted the Giorgi system with the ampere replacing the ohm in 1935, and this choice of base units is often called the MKSA system. The SI unit of magnetic flux density is Tesla, denoted by T. It is an SI unit that measures the strength and the direction of the magnetic field flowing through any area. The SI unit of magnetic field - H is amperes per meter while the SI unit of B is Teslas or Newtons per meter per ampere. 5. The practical units were based on the electromagnetic set of units rather than the electrostatic set. Corrections? The flux density is defined as the measure of the number of magnetic lines of force that pass through a cross-sectional area. [11], Also in 1935, TC1 passed responsibility for "electric and magnetic magnitudes and units" to the new TC24. A magnetic sensor is used for measuring the direction and the strength of a magnetic field. One region is a north pole (N-pole) and the other, a south pole (S-pole). Neptune has the strongest magnetic field. Determine the magnetic flux through a field that has a length of 0.50 m and a breadth of 0.60 m, where a magnetic field of 0.02 T is applied to an angle of 45o. Magnetic field lines cannot cross each other. The most familiar effects of magnetism occur in ferromagnetic materials that get strongly attracted by magnetic fields and can retain their permanent magnetic behaviour by producing magnetic fields themselves. The two flux units are Weber and Maxwell. The applications of magnetic flux include the magnetic sensor. In addition to their individual accomplishments, they built a telegraph together in 1833 . [12] To overcome these handicaps, the B.A. The anomaly was resolved at another international conference, in Chicago in 1893, by a correction in the definition of the ohm. To determine any magnetic flux density, first, the total magnetic flux should be calculated, which is generated from the magnetic field. Discovering Magnetic Fields Law of magnetic poles Permanent magnets always have two poles: regions where the magnetic field is stronger.
