Question

A magnetic substance is kept in a magnetic field, it will be thrown out of the field if it is a __________ substance.

• A. paramagnetic
• B. ferromagnetic
• C. diamagnetic
• D. antiferromagnetic

Answer 1

The correct option is C diamagnetic

Magnetic substance when kept in a magnetic field is feebly repelled or thrown out if the substance is diamagnetic. This happens because the substance is feebly magnetised in the direction opposite to that of the field. The susceptability of diamagnetic substance is negative. Paramagnetic substances are feebly attracted by a magnetic.
Ferromagnetic substances are strongly attracted by a magnet.
