The materials having negative magnetic susceptibility are (a) both paramagnetic and ferromagnetic. (b) paramagnetic. (c) diamagnetic. (d) ferromagnetic.

Answer: (c). Diamagnetic materials get magnetized opposite to the applied field, so M is opposite to H and χ = M/H 0. So the answer is (c) diamagnetic.

The materials having negative magnetic susceptibility are

Show answer and solution

Answer: (c)

Diamagnetic materials get magnetized opposite to the applied field, so $M$ is opposite to $H$ and $\chi = M/H < 0$ .
Para- and ferromagnetic materials have $\chi > 0$ .
So the answer is (c) diamagnetic.
