There is a uniform magnetic field directed perpendicular and into the plane of the paper. An irregular shaped conducting loop is slowly changing into a circular loop in the plane of the paper. Then
A
Current is induced in the loop in the anti-clockwise direction
B
Current is induced in the loop in the clockwise direction.
C
Ac is induced in the loop.
D
No current in induced in the loop.
Answer
Current is induced in the loop in the anti-clockwise direction
Explanation
Solution
Due to change in the shape of the loop, the magnetic flux linked with the loop increase hence current is induced in the loop in such a direction that it opposes the increases in flux. Therefore induced current flows in the anticlockwise direction.
