The magnetic susceptibility is negative for:
1 Paramagnetic materials only
2 Diamagnetic materials only
3 Ferromagnetic materials only
4 Paramagnetic and ferromagnetic materials
Explanation:
B Magnetic susceptibility of diamagnetic material is $\chi \lt 0$ which means that a diamagnetic material always has a negative value of magnetic susceptibility.

A metal ring is held horizontally and bar magnet is dropped through the ring with its length along the axis of the ring. The acceleration of the falling magnet is
1 equal to $g$
2 less than $g$
3 greater than $g$
4 depends on the conductivity of the ring
Explanation:
B Acceleration of the magenet will not be equal to g. It will be less than $\mathrm{g}$. This is because, as the magnet falls, amount of magnetic flux linked with the ring changes. Hence, an induced emf is developed in the ring which opposes the downward motion of the magnet.

The substances which are repelled by a magnet are called
1 diamagnetic substances
2 paramagnetic substances
3 ferromagnetic substances
4 super magnetic substances
Explanation:
A Diamagnetism substance are repelled by a strong magnetic field. The electrons in a diamagnetic material rearrange their orbits slightly creating small persistent current which oppose the external magnetic field. Two of the strongest diamagnetic field to the strongest diamagnetic material is graphite and bismuth.
