Needle `N_1 , N_2 and N_3` are made of ferromagnetic , a paramagnetic and a diamagnetic substance respectively. A magnet when brought close to them will

A

attract all three of them

B

attract `N_1` strongly , `N_2` weakly and repel `N_3` weakly

C

attract `N_1` strongly but repel `N_2 and N_3` weakly

D

attract `N_1 and N_2` strongly but repel `N_3`

Text Solution

Verified by Experts

The correct Answer is:
B
A ferromagnetic substance is strongly attracted , a paramagnetic substance is weakly attracted and a diamagnetic substance is weakly repelled by a magnet.
Thus, a magnet when brought close to needles `N_1, N_2 and N_3` will attract `N_1` strongly , `N_2` weakly and repel `N_3` weakly.
