Question

Four lightweight rod samples X, Y, Z and W are hung by threads. A bar magnet is brought near them. X is feebly repelled, Y is feebly attracted, Z is strongly attracted, and W remains unaffected. Which conclusion is correct?

G1 Physics · Accepted Answer

Step 1: Interpret the observations: weak repulsion denotes diamagnetism; weak attraction denotes paramagnetism; strong attraction denotes ferromagnetism. Step 2: Thus X is diamagnetic, Y paramagnetic, Z ferromagnetic, and W approximately non-magnetic. Step 3: The true statement is Y is a paramagnetic material. Answer D. Final answer: (D) Y is paramagnetic..
