In the given figure the North-pole of a bar magnet is being pushed towards the circular loop with constant speed.
Answer & explanation
Correct answer: option 3
As the magnet moves toward the coil, flux linked with the coil increases, hence according to the Lenz's law, it will oppose the change.
Here, the north pole is approaching the magnet, so the induced current in the face of the loop viewed from left side will flow in such a way that it will behave
like North Pole,so South pole developed in loop when viewed from right hand side
of the loop.
