Among which the magnetic susceptibility does not depend on the temperature?

  1. diamagnetism
  2. paramagnetism
  3. ferromagnetism
  4. ferrite

Answer

(1) diamagnetism

Solution

As per NCERT, diamagnetism arises from induced orbital moments and is present in all materials; its susceptibility is (nearly) independent of temperature.

Paramagnetic susceptibility follows Curie's law, = C 0T, and ferromagnetism (also ferrites) disappears above the Curie temperature, so these depend on temperature.
