Magnetic Properties of Matter: Practice Problem & Solution

33. According to Curie's law, the magnetic susceptibility of a substance at an absolute temperature $T$ is proportional to: (2003)
$1/T$
$T$
$T^{3}$
$T^{2}$

Solution Explained:

To solve this problem, we apply the core principles of Magnetic Properties of Matter. Understanding the underlying formula is key to arriving at the correct answer below:

Curie's law states that the magnetic susceptibility ($\chi$) of a paramagnetic substance is inversely proportional to its absolute temperature ($T$). Therefore, $\chi \propto 1/T$.
