Physics Question on Electromagnetic induction
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 loop changes. This is possible when the loop is rotated about a diameter
