The magnetic susceptibility is defined as:

According to Curie's law,the magnetic susceptibility of a substance at an absolute temperature $T$ is proportional to

The magnetic field $B$ and the magnetic intensity $H$ in a material are found to be $1.6 \ T$ and $1000 \ A/m$ respectively. Calculate the relative permeability $\mu_{r}$ of the material.

What is the magnetisation of a substance?

The dimensions $[MLT^{-2}A^{-2}]$ belong to:

The magnetic susceptibility of a paramagnetic substance at $-123^{\circ} C$ is $0.0060$. What will be its value at $-173^{\circ} C$?
