One cylindrical bar magnet, kept on the ...

One cylindrical bar magnet, kept on the axis of one circular coil. Now if this magnet is rotated about this axis, then ____

A

current will flow in the coil.

B

current will not flow in the coil.

C

only emf will be induced.

D

emf and current both will be induced.

Text Solution

Verified by Experts

The correct Answer is:
B
Because here, magnetic flux associated with the coil, does not change.
