Faraday Law which is the fundamental law of electromagnetism demonstrating how a magnetic field will interact with an electric field to produced electromotive force (EMF) and this phenomenon is called electromagnetic induction
In 1831, Micheal Farady formulated two laws on the basis of their experiments
This law is the fundamental principle of electrical motor ,Generator and transformer
Faraday First law states
“whenever a conductor is placed inside a varying magnetic field , emf will induced in the conductor and this emf is called induced emf evermore if the conductor circuit are closed then current will also flow through conductor which is called induced current .
When a conductor is rotated in a magnetic field ,emf will induced which is called induced emf .
emf is induced electromotiveforce
Negative sign according to Len;s law
N is No of loops
d@/dt is the rate of change of flux linkages with time
The current from the induced emf will produced a magnetic field and this magnetic field which will always oppose the original change in the magnetic field .
Application of Faraday Law
Faraday Law of electromagnetic induction has found many application including many electrical things such as inductors, transformer, motor ,generator and many more,
