Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): When a diamagnetic material is placed in a non-uniform magnetic field, it tends to move from the stronger to the weaker part of the field. Reason (R): The magnetic susceptibility ( ) of a diamagnetic material is small and positive. In the light of the above statements, choose the most appropriate a

Options

  1. ABoth Assertion (A) and Reason (R) are correct and Reason (R) is the correct explanation of Assertion (A)
  2. BBoth Assertion (A) and Reason (R) are correct but Reason (R) is not the correct explanation of Assertion (A)
  3. CAssertion (A) is correct but Reason (R) is incorrect
  4. DAssertion (A) is incorrect but Reason (R) is correct

Correct answer

C. Assertion (A) is correct but Reason (R) is incorrect

Step-by-step solution

Assertion (A) is correct: Diamagnetic materials develop an induced magnetic moment in a direction opposite to the applied magnetic field. As a result, they are feebly repelled by magnets and tend to move from the stronger to the weaker part of a non-uniform magnetic field. Reason (R) is incorrect: The magnetic susceptibility ( ) of a diamagnetic material is small and negative ( -1 Answer: Assertion (A) is correct but Reason (R) is incorrect
