Magnetization of the sample is
1 Volume of the sample per unit magnetic dipole moment
2 ratio of pole strength to magnetic dipole moment
3 ratio of magnetic dipole moment and pole strength
4 net magnetic dipole moment per unit volume
Explanation:
D Magnetisation of a sample is defined as the magnetic moment per unit volume of the sample. It is represented by $\mathrm{M}$. And, magnetisation of sample is given by- $\mathrm{M}=\frac{\mu}{\mathrm{V}}$ Note-SI unit for it $\rightarrow \mathrm{Am}^{-1}$.
