Explain induced potential difference (or electromotive force) and induced electric current . On what factor does induced potential differnce (or electromotive force) depend ?

Explanation

Because of the rate of change of number of magnetic field lines linked with the loop during the relative motion of a magnet and loop or due to a changing current in a nearby conductor an electric potenital difference is induced in the coil . It is called induced potential difference ( or electromotive force).
Due to this electric current .
The electromotive froce induced in a loop is proportional to the rate of change of number of magnetic field lines associated with the loop and the number of turns of a loop .
Important notes :
(1) Induced current is (i) proportionl to induced electromotive force and (ii) inversely proportional to teh resistance in the circuit .
(2) If the circuit is open , there can be induced electromotive force but there is no current .
