Question

Curie’s law is applicable at every point on a Paramagnetic Material.

(a) True

(b) False

This question was posed to me in final exam.

This intriguing question comes from Classification of Magnetic Materials in division Magnetic Properties of Materials of Engineering Physics II

Answer 1

Right option is (b) False

The explanation: As the field is increased or the temperature is lowered, the magnetization increases until it reaches the saturation value, at which point all the dipoles are perfectly aligned with the field. Beyond this, Curie’s law is no longer valid.
