A conducting ring is placed in a uniform magnetic field with its plane perpendicular to the field . An `emf` is induced in the ring if

A

it is rotated about its axis.

B

it is rotated about its diameter.

C

it is not moved.

D

it is given translational motion in the field.

Text Solution

Verified by Experts

The correct Answer is:
B
An emf is induced only when magnetic flux linked with the loop changes. This is possible when the loop is rotated about a diameter
