Question

A substance which is feebly repelled by magnet is a ___________

• A. diamagnetic substance
• B. paramagnetic substance
• C. ferromagnetic substance
• D. none of the above

Answer 1

The correct option is A

diamagnetic substance

1. Diamagnetic substances are those substances that when placed in a magnetic field are weakly magnetized in a direction opposite to the applied field.
2. Ferromagnetic substances are those substances that when placed in a magnetic field are strongly magnetized in the same direction as the applied field.
3. Paramagnetic substances are those substances that when placed in a magnetic field weakly magnetized in the same direction as the applied field.
4. Diamagnetic substances are repelled by the magnet whereas paramagnetic substances are attracted by a magnet.

Hence, a substance that is feebly repelled by the magnet is a diamagnetic substance.

The correct option is (A).
