Question

Explain Faradey's experiment on EMI.

Answer 1

While studying magnetism we learned that electricty and magnetism are interrelated and infact moving charges or electric currents produces magnetic field that can deflect magnetic compass needle
A question arises,can moving magnetic field produce electricty .Answer is yes and it was first showed by a british scientist Michael faraday in 1931 who after performing various experiments found that moving magnetic field can give rise to the EMF
Independently the effect was discovered by Joseph Henry in USA at about the same time
In this chapter we will discuss about the electric and magnetic field changing with time
More precisely we will consider the phenomenon related to time changing current or time changing magnetic fields
(2) Faraday's experiment
faraday in 1831 first discovered that whenever the number it of magnetic lines of forces in a circuit changes ,a emf is produced in the circuit and is known as induced emf and this phenomenon is known as Electro Magnetic Induction
If the circuit is closed one then a current flows through it which is known an induced current
This induced emf and current lasts only for the time while magnetic flux is chnaging
We now illustrate two examples of the sort that faraday and henry performed.

Hope this will help you.. ✌

Answer 2

1. Faraday in 1831 first discovered that whenever the number it of magnetic lines of forces in circuit changes, a emf is produced in the circuit and in known as enduced emf and his phenomenon is known as Electro Magnetic Induction.
2. if the circuit is closed one tgen a current flows through it which is known an induced current.
3. this enduced emf and current last only for the time while magnetic flux is changing.
4. we know illustrate two examples of the sort that Faraday and Henry performed

i hope it's helpful to you
