For which of the following substances, the magnetic susceptibility is independent of temperature? (a) Diamagnetic only. (b) Paramagnetic only. (c) Ferromagnetic only. (d) Diamagnetic and paramagnetic both.

Answer: (a). Paramagnetic: χ ∝ 1/T. Ferromagnetic: χ depends strongly on T. Diamagnetism comes from induced orbital motion, unaffected by thermal agitation, so its χ is independent of T. So the answer is (a) diamagnetic only.

For which of the following substances, the magnetic susceptibility is independent of temperature?

Show answer and solution

Answer: (a)

Paramagnetic: $\chi \propto \dfrac{1}{T}$ . Ferromagnetic: $\chi$ depends strongly on $T$ .
Diamagnetism comes from induced orbital motion, unaffected by thermal agitation, so its $\chi$ is independent of $T$ .
So the answer is (a) diamagnetic only.
