Question

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

• 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: (B)

Diamagnetic substances are weakly magnetised in a direction opposite to that of applied magnetic field. These are repelled in an external magnetic field, i.e., have a tendency to move from high to low field region.
