Assertion: Diamagnetism is universal, it is present in all materials
Reason: Field due to induced magnetic moment is opposite to the magnetising field.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true and reason is not the correct explanation of assertion.

C

If assertion is ture but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Diamagnetism is when a material acquires amagnetisation in the opposite direction to the applied magnetic field. As a magnetic field will always induce magnetism, diamagnetism will occur in all substances. The magnitude may be small and be overcome by other para or ferromagnetic properties.
