Vedclass · Answer

(A) Ferromagnetic substances are strongly attracted by a magnetic field because they possess permanent magnetic domains that align easily with the external field.Paramagnetic substances are weakly attracted by a magnetic field because they possess permanent magnetic dipoles that align weakly with the external field.Diamagnetic substances are weakly repelled by a magnetic field because they develop an induced magnetic moment in a direction opposite to the applied field due to the orbital motion of electrons.Therefore,the magnet will attract $N_1$ strongly,$N_2$ weakly,and repel $N_3$ weakly.

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