The discovery and understanding of electromagnetic induction are based on a long series of experiments carried out by Faraday and Henry. From the experimental observations, Faraday concluded that an emf is induced in the coil when the magnetic flux across the coil changes with time. Therefore, Faraday\u2019s first law of electromagnetic induction states the following:<\/p>\n\n\n\n
Whenever a conductor is placed in a varying magnetic field, an electromotive force is induced. If the conductor circuit is closed, a current is induced, which is called induced current.<\/p>Mentioned here are a few ways to change the magnetic field intensity in a closed loop:
By rotating the coil relative to the magnet.
By moving the coil into or out of the magnetic field.
By changing the area of a coil placed in the magnetic field.
By moving a magnet towards or away from the coil.
Faraday\u2019s Second Law of Electromagnetic Induction
Faraday\u2019s second law of electromagnetic induction states that
The induced emf in a coil is equal to the rate of change of flux linkage.
The flux is the product of the number of turns in the coil and the flux associated with the coil. The formula of Faraday\u2019s law is given below:
\u03b5=\u2212N\u0394\u03d5\/\u0394t
Where \u03b5 is the electromotive force, \u03a6 is the magnetic flux, and N is the number of turns.<\/cite><\/blockquote>\n","protected":false},"excerpt":{"rendered":"Faraday\u2019s law of electromagnetic induction, also known as Faraday\u2019s law, is the basic law of electromagnetism which helps us to predict how a magnetic field would interact with an electric circuit to produce an electromotive force (EMF).
