The closed loop (PQRS) of wire is moved into a uniform magnetic field

1.	The closed loop (PQRS) of wire is moved into a uniform magnetic field at right angles to the plane of the paper as shown in the figure. Predict the direction of the induced current in the loop.
Answer» By Lenz’s law, the direction of induced current is such that it opposes its own cause of production. The induced current opposes the increase in magnetic flux. Hence the direction of induced current is PSRQP (anticlockwise).
