A conducting loop is placed in a uniform magnetic field with its plane perpendicular to the field. An emf is induced in the loop if
A
It is rotated about its axis.
B
It is rotated about a diameter.
C
It is not moved.
D
It is given translational motion in the field.
Answer
It is rotated about a diameter.
Explanation
Solution
An emf is induced only when magnetic flux linked with the loops changes this is possible when the loop is rotated about a diameter.
