Question

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

• A. Attracted by both the poles
• B. Repelled by both 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 both the poles

When diamagnetic materials subjected to an external magnetic field, an internal field is induced in it in a direction opposite to 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.
