When the switch Sis closed in the figure given below, the pointer of the galvanometer moves to the right.

If S is kept closed, will the pointer:

The essential difference between an AC generator and a DC generator is that:

Each one of the following changes will increase e.m.f. (or voltage) in a simple generator except:

The north pole of a long bar magnet was pushed slowly into a short solenoid connected to a galvanometer. The magnet was held stationary for a few seconds with the north pole in the middle of the solenoid and then withdrawn rapidly. The maximum deflection of the galvanometer was observed when the magnet was:
