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

Options

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 is induced in the loop.

Answer

A

Explanation

Due to change in the shape of the loop, the hence, current is induced in the increases 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
