Definition
The magnetization of a material is defined as its magnetic moment per unit volume. Like the magnetic moment, it is a vector quantity and function of position, e.g., $M(r)$. The total magnetic moment of a body is given by the integral over its volume:
 * $$\mathbf{m}=\iiint \mathbf{M}(\mathbf{r})\,d^3\mathbf{r}.$$

Units
As a magnetic moment per unit volume, magnetization is represented by the symbol $M$ and has units of amperes per meter (A/m) in SI units (emu/cm3 in cgs units). Referred to as the magnetic polarization or intensity ($J$ or $I$), it is measured in teslas in the SI system (but still emu/cm3 in cgs). It can also be given as magnetic moment per unit mass ($M$ or $&sigma;$) with units A m2 / kg in SI units.
