A) a ferromagnetic substance becomes paramagnetic
B) a paramagnetic substance becomes diamagnetic
C) a diamagnetic substance becomes paramagnetic
D) a paramagnetic substance becomes ferromagnetic
Correct Answer: A
Solution :
Ferromagnetism decreases with rise in temperature. If we heat a ferromagnetic substance, then at a definite temperature the ferromagnetic property of the substance suddenly disappears and the substance becomes paramagnetic. The temperature above which a ferromagnetic substance becomes paramagnetic is called the Curie temperature of the substance.
