What is the magnetisation of a substance?
(N/A) Magnetisation $(M)$ of a substance is defined as the net magnetic dipole moment per unit volume of the material.
Mathematically,it is expressed as:
$M = \frac{m_{net}}{V}$
where $m_{net}$ is the net magnetic dipole moment and $V$ is the volume of the substance.
The $SI$ unit of magnetisation is $A/m$ (ampere per meter).
