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)
$1/T$
$T$
$T^3$
$T^2$

Short Solution (Best for NEET):

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:

According to Curie's law for paramagnetic substances, magnetic susceptibility is inversely proportional to absolute temperature $T$, i.e., $\chi = \frac{C}{T}$, or $\chi \propto 1/T$.
