Faraday’s laws of electromagnetic induction are:
(a) First law : Whenever there is a change in the magnetic flux associated with a circuit, an electromagnetic field is induced in the circuit.
(b) Second law : The magnitude of the induced electromagnetic field is directly proportional to the time rate of change of magnetic flux through the circuit.
Lenz law states that the direction of induced current is such as to oppose the change that produces it.
Final Answer:
Hence, Faraday’s laws of electromagnetic induction are whenever there is a change in the magnetic flux associated with a circuit, an electromagnetic field is induced in the circuit and the magnitude of the induced electromagnetic field 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.
