Question

describe an activity with diagram to show that current is induced in a coil when magnatic field around it is changed ?

Answer 1

araday discorved that when mf is changed around a coil a v is induced in it.let e take a solenide with insulated cu wiring on it when we bring magnet near the solenoid voltage is induced in one direction when we change polarity they induced in other direction this is due to flux change

induced voltage=change in flux with respect to time

Answer 2

faraday discorved that when mf is changed around a coil a v is induced in it.let e take a solenide with insulated cu wiring on it when we bring magnet near the solenoid voltage is induced in one direction when we change polarity they induced in other direction this is due to flux change

induced voltage=change in flux with respect to time
