A ball of superconducting material is dipped in liquid nitrogen and placed near a bar magnet. (i) In which direction will it move? (ii) What will be the direction of it's magnetic moment?

Text Solution

Verified by Experts

Superconducting material and liquid nitrogen are both diamagnetic in nature. The ball will behave as a diamagnetic material.
(i) It will move away from the bar magnet when placed near it. (ii) It will be opposite to the direction of magnetic moment of bar magnet.
