Options

• attract N₁ strongly, N₂ and N₃ weakly

• attract N₁ strongly and N₂ weakly, repel N₃ weakly

• attract N₂ strongly, N₁ and N₃ weakly

• attract N₁ strongly, repel N₂ and N₃ weakly

Answer 1

There are three needles 'N₁', 'N₂' and 'N₃' made of a ferromagnetic, a paramagnetic and a diamagnetic substance respectively. When a magnet is brought close to them, then it will attract N₁ strongly and N₂ weakly, repel N₃ weakly.
