Question

How does the magnetic susceptibility of a paramagnetic material vary with its absolute temperature under Curie's Law?

Options

• It varies inversely with \[T-T_C\]

• It varies inversely with its absolute temperature

• It remains very large and positive at every temperature

• It becomes small and negative as absolute temperature increases

Answer 1

Curie's Law states that paramagnetic susceptibility varies inversely with absolute temperature. Thus, its temperature dependence is \[\chi_m\propto\frac{1}{T}\].
