Question

As shown below, a coil is in a magnetic field that is directed upward. If the magnitude of the magnetic field increases, in what direction does the induced current flow in the coil? Explain. Suppose you know that a deflection of the galvanometer needle to the right means that current is flowing into the galvanometer as indicated: A bar magnet is moved towards a coil as shown in the picture below. The galvanometer needle deflects to the left. Replace the question marks on the magnet with the appropriate North and South markings. Briefly explain your reasoning.

Explanation / Answer

1) Using right hand rule

The direction of induced current is in anticlockwise sense.

2) To deflect the needle in left direction current in the coil should move in anticlockwise direction. It will happen only when north pole of bar magnet move towards the coil.

So towards the coil N-pole and away is S-pole
