2. List of electromagnetism equations - Wikipedia

   en.wikipedia.org/wiki/List_of_electromagnetism...

   The definitions for monopoles are of theoretical interest, although real magnetic dipoles can be described using pole strengths. There are two possible units for monopole strength, Wb (Weber) and A m (Ampere metre). Dimensional analysis shows that magnetic charges relate by q m (Wb) = μ 0 q m (Am).

3. Mathematical descriptions of the electromagnetic field

   These equations are inhomogeneous versions of the wave equation, with the terms on the right side of the equation serving as the source functions for the wave. As with any wave equation, these equations lead to two types of solution: advanced potentials (which are related to the configuration of the sources at future points in time), and ...

4. Gauss's law for magnetism - Wikipedia

   en.wikipedia.org/wiki/Gauss's_law_for_magnetism

   For zero net magnetic charge density (ρ m = 0), the original form of Gauss's magnetism law is the result. The modified formula for use with the SI is not standard and depends on the choice of defining equation for the magnetic charge and current; in one variation, magnetic charge has units of webers , in another it has units of ampere - meters .

   The equations in this section are valid for electromagnets for which: the magnetic circuit is a single loop of core material, possibly broken by a few air gaps; the core has roughly the same cross-sectional area throughout its length. any air gaps between sections of core material are not large compared with the cross-sectional dimensions of ...

6. Magnetization - Wikipedia

   en.wikipedia.org/wiki/Magnetization

   The magnetization field or M-field can be defined according to the following equation: =. Where is the elementary magnetic moment and is the volume element; in other words, the M-field is the distribution of magnetic moments in the region or manifold concerned.

7. Permeability (electromagnetism) - Wikipedia

   en.wikipedia.org/wiki/Permeability...

   Paramagnetic materials are attracted to magnetic fields, hence have a relative magnetic permeability greater than one (or, equivalently, a positive magnetic susceptibility). The magnetic moment induced by the applied field is linear in the field strength, and it is rather weak. It typically requires a sensitive analytical balance to detect the ...
