According to Curie’s law, the magnetic susceptibility of a substance at an absolute temperature T is proportional to:

1. T²
2. 1/T
3. T
4. 1/T²

Correct answer: 1/T

Solution

Curie's law states that the magnetic susceptibility (χ) of a paramagnetic material is inversely proportional to its absolute temperature (T), i.e., χ ∝ 1/T.
