Question

State Faraday's laws of electromagnetic induction and Lenz's law.

Answer 1

Faraday's laws of electromagnetic induction.
(a) First law : Whenever there is a change in the magnetic flux associated with a circuit, an e.m.f. is induced in the circuit.
(b) Second law : The magnitude of the induced e.m.f. is directly proportional to the time rate of change of magnetic flux through the circuit.
Lenz law : The direction of induced current is such as to oppose the change that produces it.
