What is Faraday's law and Lenz law?

What is Faraday’s law and Lenz law? Faraday’s laws describe how an electric current produces a magnetic field and conversely how a change in the magnetic field will produce a current through the conductor. There are two laws of electromagnetic induction as stated by Michael Faraday.

I Law: Whenever there is a change in the magnetic flux linked with a circuit an emf and hence a current is induced in the circuit. The induced emf lasts as long as the change in flux persists.

II Law: The magnitude of the induced emf is directly proportional to the rate of the change of magnetic flux linked with the circuit.

The direction of the induced current in the circuit is given by Lenz’s law. According to the law, the induced current is always in such a direction as to oppose the cause which is producing it.
