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 answer from the options given below:
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 answer from the options given below:
Options
- ABoth Assertion (A) and Reason (R) are correct and Reason (R) is the correct explanation of Assertion (A)
- BBoth Assertion (A) and Reason (R) are correct but Reason (R) is not the correct explanation of Assertion (A)
- CAssertion (A) is correct but Reason (R) is incorrect
- 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 (). It is paramagnetic materials that have a small and positive susceptibility.
Answer: Assertion (A) is correct but Reason (R) is incorrect
Reason (R) is incorrect: The magnetic susceptibility () of a diamagnetic material is small and negative (). It is paramagnetic materials that have a small and positive susceptibility.
Answer: Assertion (A) is correct but Reason (R) is incorrect
