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