Magnetization

The magnetization M of a dielectric is defined by

(1)

where N is the number of magnetic dipoles per unit volume and is the magnetic dipole moment per dipole (Griffiths 1998, p. 220). The magnetization can also be written as

(2)

where is the magnetizability.

The effect of magnetization is to induce bound current densities

(3)

inside a material and a bound surface current

(4)

on its surface, where is the outward-pointing unit normal.
