Question

A loop of irregular shape of conducting wire P Q R S (as shown in figure) placed in a uniform magnetic field) perpendicular to the plane of the paper changes into a circular shape. The direction of induced current will be (A) Clockwise (B) Anti-clockwise (C) No current (D) None of these

Tardigrade Admin · Accepted Answer

Using Lenz's law, inward flux is increasing. So to oppose this change current will be anticlockwise
