When current carrying coil is moved towards the coil connected in series with a galvanometer, the pointer in the galvanometer G
The induced electromotive force in any closed circuit is equal to the negative of the time rate of change of the magnetic flux enclosed by the circuit.
induced emf for a coil having 1 turns will be
The flux of all the turns will be added up. So the induced emf for a coil having N turns will be
