Q6.2 (a) Use Lenz’s law to determine the direction of induced current in the
situations described by Fig. 6.19: a
A wire of irregular shape turning into a circular shape;
By turning the wire from irregular shape to circle, we are increasing the area of the loop so flux will increase so current will induce in such a way that reduces the flux through it. By right-hand thumb rule direction of current is adcba.
