Q.Define magnetization. Write its SI unit and dimensions.

Magnetization measures how strongly a material has been magnetized, defined analogously to 'moment per unit volume', with the same units as the magnetic field intensity $H$.

Definition: Magnetization $M$ of a magnetic material is defined as the net magnetic dipole moment per unit volume of the material:

$M = \frac{m_{\text{net}}}{V},$

where $m_{\text{net}}$ is the resultant magnetic moment of all the atomic dipoles in the sample, and $V$ is its volume. It quantifies the degree to which the material has become magnetized under an applied field.
