A small cylinder made of a diamagnetic material is brought near a bar magnet. One end of the cylinder is brought near the North pole of the magnet and is repelled. What happens when the other end of the cylinder is brought near the North pole of the magnet? (A) The other end of the cylinder will be repelled by the magnet. (B) The other end of the cylinder will not be affected by the magnet. (C) The other end of the cylinder will be attracted more strongly by the magnet. (D) The other end of the cylinder will be attracted less strongly by the magnet. (E) The other end of the cylinder will be attracted by the magnet.

Answer: Option (A) is the correct answer.

Explanation:

A diamagnetic material does not contain any unpaired electrons and therefore, in a magnetic field direction they will always flow in the direction opposite to the magnetic field.

Hence, a diamagnetic material will always repel the magnetic field whenever it comes in contact with that.

Thus, we can conclude that when the other end of the cylinder is brought near the North pole of the magnet then the other end of the cylinder will be repelled by the magnet.
