Vedclass · Answer

(B) According to the Curie-Weiss law for ferromagnetic materials above the Curie temperature,the magnetic susceptibility $\chi_m$ is inversely proportional to the temperature difference $(T - T_c)$. However,in the context of standard textbook problems where Curie's law $\chi_m \propto \frac{1}{T}$ is applied to magnetic materials:Given:$T_1 = 30\,^{\circ}	ext{C} = 30 + 273 = 303\,	ext{K}$$T_2 = 333\,^{\circ}	ext{C} = 333 + 273 = 606\,	ext{K}$Using the relation $\chi_m \propto \frac{1}{T}$:$\frac{\chi_1}{\chi_2} = \frac{T_2}{T_1}$Substituting the values:$\frac{\chi}{\chi_2} = \frac{606}{303} = 2$Therefore,$\chi_2 = \frac{\chi}{2} = 0.5\,\chi$.

At a temperature of $30\,^{\circ}\text{C}$,the susceptibility of a ferromagnetic material is found to be $\chi$. Its susceptibility at $333\,^{\circ}\text{C}$ is......$\chi$.
