Question

If a diamagnetic substance is brought near the north or south pole of a bar magnet, it is

• A. attracted by the poles
• B. repelled by the poles
• C. repelled by the north pole and attracted by the south pole
• D. attracted by the north pole and repelled by the south pole

Answer 1

The correct option is B repelled by the poles

Diamagnetic materials create an induced magnetic field in a direction opposite to an externally applied magnetic field and are repelled by the applied magnetic field. Hence, if a diamagnetic substance is brought near the north or the south pole of a bar magnet, it is repelled by the both the poles.
