According to Lenz's law of electromagnetic induction

A

The induced e.m.f. is not in the direction opposing the change in magnetic flux

B

The relative motion between the coil and magnet produces change in magnetic flux

C

Only the magnet should be moved towards coil

D

Only the coil should be moved towards magnet

Text Solution

Verified by Experts

The correct Answer is:
B
The relative motion between the coil and the magnet produces change in the magnetic flux in the coil and induced emf is always in such a direction that it opposes the change in the flux.
