Q. 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 anticlockwise 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
Explanation
(a) As the shape of the loop is changing and hence, the flux linked with the loop changes. There will an induced emf hence, induced current in the coil. Applying right hand screw rule we get induced current in anticlockwise direction.
