Question 113: Magnetism and Matter

Question

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

Accepted Answer

Ferromagnetic substance has magnetic domains whereas para-magnetic substances have magnetic dipoles which get attracted to a magnetic field. Diamagnetic substances do not have magnetic dipole but in the presence of external magnetic field due to their orbital motion of electrons these substances are repelled.

Answer

attract $${N_1}$$ and $${N_2}$$ strongly but repel $${N_3}$$

Answer

attract $${N_1}$$ strongly, $${N_2}$$ weakly and repel $${N_3}$$ weakly

Answer

attract $${N_1}$$ strongly, but repel $${N_2}$$ and $${N_3}$$ weakly

Answer

attract all three of them
