A bar magnet with

Answer :

Pushing the North Pole of the magnet towards a coil induces the current in the coil such that forward motion of the North Pole is opposed.

In order to oppose the motion the face of the coil opposite to the North Pole should also behave like a north pole.

Thus the current is induced in the anticlockwise direction. The figure below illustrates the generated induced current.

Here B = Magnetic field;

V = velocity of magnet;

I = induced current.
