Write the results of Faraday's experiment performed with bar magnet and insulated conducting coil.

Text Solution

Verified by Experts

(1) The relative motion between the magnet and the coil (or between the two coils) is responsible for generation (induction) of electric current in the coil.
(2) If the relative motion between the magnet and the coil is increased/ decreased, more! less current is induced.
(3) The direction of induced current is reversed, if the direction of relative motion is reversed.
(4) If the magnet and the coil (or two coils) are moving with same speed in the same direction (if their relative velocity is zero), no current is induced in the coil.
(5) When magnetic flux linked with closed circuit (loop) changes then induced emf and induced current is produced.
(6) Magnitude of induced emf is proportional to rate of change of magnetic flux linked with circuit.
