Nickel shows ferromagnetic property at r...

Nickel shows ferromagnetic property at room temperature. If the temperature is increased beyond curie temperature, then it will show

A

Anti-ferromagnetism

B

No magnetic property

C

Diamagnetism

D

Paramagnetism

Text Solution

Verified by Experts

The correct Answer is:
D

On heating, ferromagnetic substances lose its magnetization and become paramagnetic in nature because the partial alignment of some small atomic magnets in the ferromagnetic substance is distorted.
