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:
Option: 1
current is induced in the loop in the anti-clockwise direction
Option: 2
current is induced in the loop in the clockwise direction
Option: 3
ac is induced in the loop
Option: 4
no current in induced in the loop
Answers (1)
Due to change in the shape of the loop, the magnetic flux lined with the loop 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.
