Question

What is Faraday Law of electromagnetic induction .
State the expression of motional electromotive force .​

Answer 1

Answer:

Explanation:

The Faraday's Law of electromagnetic induction. The emf, E, produced around a loop of conductor is proportional to the rate of change of the magnetic flux, φ, through the area, A, of the loop. This can be stated mathematically as: E=−NΔϕΔt

Answer 2

Explanation:

Faraday's Law of ( EMI ) :

Faraday's First law :

Whenever there is change in magnetic flux with a conductor , an Emf is induced in the conductor ( if the conductor form a closed coil an induced current flow through it ).

Faraday's Second law :

The magnitude of induced emf is directly proportional to " Rate of change in magnetic flux "

$emf \: = \frac{change in \: magnetic \: flux}{change \: in \: time}$

The induced emf can be increase by increasing the number of turn N of a closed coil.
