In this model, a magnetic H-field is produced by fictitious magnetic charges that are spread over the surface of each pole. These magnetic charges are in fact related to the magnetization field M. The H-field, therefore, is analogous to the electric field E, which starts at a positive electric charge and ends at a See more A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its … See more Permanent magnets are objects that produce their own persistent magnetic fields. They are made of ferromagnetic materials, such as … See more Currents of electric charges both generate a magnetic field and feel a force due to magnetic B-fields.

WebB-field is a magnetic field defined by the force it exerts on a moving charged particle, whereas an H-field is similar to a B-field except when they are inside a material. However, they are measured differently. In the SI System: B is measured in teslas represented as T. Whereas the H-field is measured in amperes per metre (A/m). WebH = B/μ m = B/μ 0 - M and has the value of unambiguously designating the driving magnetic influence from external currents in a material, independent of the material's magnetic response. The relationship for B can be written in the equivalent form B = μ 0 (H + M) H and M will have the same units, amperes/meter. http://www.dannex.se/theory/3.html bush blocks for sale central west nsw
