You are given three magnetic needles $N_F, N_p$ and $N_D$ made up of ferromagnetic, paramagnetic and diamagnetic materials respectively.

If a magnet is brought close to each of the needle one by one, then the magnet will

Options:

attract all three of them equally

attract $N_F$ strongly, but repel $N_p$ and $N_D$ weakly

attract $N_F$ strongly and $N_p$ weakly but repel $N_D$ weakly

attract $N_F$ and $N_p$ strongly but repel $N_D$ strongly

Correct Answer:

attract $N_F$ strongly and $N_p$ weakly but repel $N_D$ weakly

Explanation:

The correct answer is Option (3) → attract $N_F$ strongly and $N_p$ weakly but repel $N_D$ weakly
