Question

$(A)$ According to Curie's law, the magnetic susceptibility $\chi$ of paramagnetic substances is inversely proportional to the absolute temperature $T

Vedclass · Accepted Answer

Both statement-$I$ and statement-$II$ are true.

Vedclass · Answer

$(A)$ According to Curie's law, the magnetic susceptibility $\chi$ of paramagnetic substances is inversely proportional to the absolute temperature $T$, given by $\chi = \frac{C}{T}$.For ferromagnetic substances, the susceptibility follows the Curie-Weiss law: $\chi = \frac{C}{T - T_C}$, where $T_C$ is the Curie temperature. As $T$ decreases towards $T_C$, the susceptibility increases. Thus, Statement-$I$ is true.Diamagnetism arises due to the orbital motion of electrons. When an external magnetic field is applied, it induces a change in the orbital motion, creating a magnetic moment that opposes the applied field (Lenz's law at the atomic level). Thus, Statement-$II$ is true.Therefore, both statements are true. The correct option is $(A)$.
