Given below are two statements:
Statement – I : Susceptibilities of paramagnetic and ferromagnetic substances increase with decrease in temperature.
Statement – II: Diamagnetism is a result of orbital motions of electrons developing magnetic moments opposite to the applied magnetic field.
Choose the CORRECT answer from the options
given below : -

According to curie's law, magnetic susceptibility is inversely proportional to temperature for a fixed value of external magnetic field i.e. $\mathrm{\chi }=\frac{\mathrm{C}}{\mathrm{T}}$.

The same is applicable for ferromagnet & the relation is given as $\chi =\frac{\mathrm{C}}{\mathrm{T}-{\mathrm{T}}_{\mathrm{C}}} \left({\mathrm{T}}_{\mathrm{C}}\right.$ is curie temperature) Diamagnetism is due to non-cooperative behaviour of orbiting electrons when exposed to external magnetic field.
