Question

  • Assertion (A): Diamagnetic substances exhibit magnetism.
  • Reason (R): Diamagnetic materials do not have a permanent magnetic dipole moment.

Options

  • Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

  • Both Assertion (A) and Reason (R) are true and Reason (R) is NOT the correct explanation of Assertion (A).

  • Assertion (A) is true and Reason (R) is false.

  • Assertion (A) is false and Reason (R) is also false.

MCQ

Solution

Assertion (A) is true and Reason (R) is false.

Explanation:

Diamagnetic material does not have permanent dipole moment but it can exhibit magnetism. Hence assertion is true and reason is false.
