Faraday’s Law of Electromagnetic Induction

Chapter-6|Electromagnetic Induction (EMI)| NCERT 12th Physics:

Faraday’s Law of Electromagnetic Induction:

The two laws of electromagnetic induction given by Faraday are as under.

1. Faraday’s First Law: Whenever there is a relative motion between a magnet and a coil, then magnetic flux linked with coil changes and an EMF is induced in the coil. If conductor is a closed coil and induced current flows in it.

The EMF induced is called induced EMF and current due to it is called induced current.

2. Faraday’s Second Law: The magnitude of induced EMF in a circuit is equal to the rate of change of magnetic flux through the circuit.

Induced EMF ∝ Rate of change of magnetic flux.
