Consider the following two statements A and B and identify the correct choice in the given answers A. Paramagnetism is explained by domain theory. B. Susceptibility of a diamagnetic substance is independent of temperature.

A

Both A and B are correct

B

Both A and B are wrong

C

A is correct and B is wrong

D

A is wrong and B is correct

Text Solution

Verified by Experts

The correct Answer is:
D

Domain theory explains only ferromagnetism. Hence statement (A) is wrong.
Susceptibility of a diamagnetic substance is independent of temperature but para and ferromagnetic substances depends on temperature. Hence statement (B) is correct.
