State Faraday's Laws of Electromagnetic Induction.

Electromagnetic Induction:

In simple words, electromagnetic induction is referred to as the generation of electromotive force (EMF) in an electrical conductor when a varying magnetic field is applied to it.

Faraday's Laws of Electromagnetic Induction:

There are two Faraday's laws of Electromagnetic Induction that assist in predicting how the magnetic field applied to a conductor will interact with it to produce EMF.

1. Faraday's first law states that any change in the magnetic field of a coil of wire will cause an emf to be induced in the coil. This emf induced is called induced EMF. The current produced because of this is called induced current. There are multiple ways to vary the magnetic field. Some of them are listed below:
   1. By moving a magnet towards or away from the coil.
   2. By moving the coil into or out of the magnetic field.
   3. By changing the area of a coil placed in the magnetic field.
   4. By rotating the coil relative to the magnet.
2. Faraday's second law states that the magnitude of emf induced in the coil is equal to the rate of change of flux that linkages with the coil. The flux linkage of the coil is the product of the number of turns in the coil and the flux associated with the coil. The formula for Faraday's law is given below:

$E=-N\frac{d\varphi }{dt}$

where E is the induced EMF, $\varphi$ is the magnetic flux.

These are the Faraday's Laws of Electromagnetic Induction.
