Faraday’s Laws of Electromagnetic Induction

Electromagnetic Induction

The phenomenon of production of e.m.f. and hence current in a conductor or coil when the magnetic flux linking the conductor or coil changes is called electromagnetic induction.

There are two laws of electromagnetic induction, that are explained below:-

Faraday’s First Law of Electromagnetic Induction

This law states that, when the magnetic flux linking a conductor or coil changes, an e.m.f. is induced in it. It does not matter how the change in magnetic flux is brought about. The summary of the first law of electromagnetic is that the induced e.m.f. develop in a circuit subjected to a changing magnetic field.

Faraday’s Second Law of Electromagnetic Induction

The magnitude of the e.m.f. induced in a conductor or coil is directly proportional to the rate of change of flux linkage.

[…] not be any self induced emf in the primary winding to oppose the applied voltage. According to the Faraday’s law of electromagnetic induction, whenever a conductor cuts by the varying magnetic flux an emf is induced in the conductor. But […]
