Q. A magnet is dropped into an infinitely long vertical copper tube. Then

Assertion :

A bar magnet is dropped into a long vertical copper tube. Even taking air resistance as negligible, the magnet attains a constant terminal velocity. If the tube is heated, the terminal velocity gets increased.

Reason :

The terminal velocity depends on the eddy current produced in the bar magnet.
