As the temperature increases up to the Curie temperature, the relative susceptibility of ferromagnetic materials?

(a) Increases

(b) Decreases

(c) Remains constant

(d) Becomes zero

This question was posed to me in homework.

The query is from Relative Permeability in section Simple Magnetic Circuits of Basic Electrical Engineering

Best answer
Correct choice is (a) Increases

The best I can explain: The susceptibility of ferromagnetic materials increases with the increase in temperature and then it decreases when the temperature goes beyond the Curie temperature.
