Answer:
Electromagnetic Induction or Induction is a process in which a conductor is put in a particular position and magnetic field keeps varying or magnetic field is stationary and a conductor is moving. This produces a Voltage or EMF (Electromotive Force) across the electrical conductor.
hope this 'll help u
Electromagnetic induction is the production of voltage across conductor, especially when it is exposed to a magnetic field that is changing.
Michael Faraday discovered electromagnetic induction in 1831. So, as you can see, it was discovered at a very early period of time from now.
Electromagnetic induction can also be explained like this: It is a process where a conductor placed in a changing magnetic field (or a conductor moving through a stationary magnetic field).
It causes the production of a voltage across the conductor, as you already saw above.
The formal name for the physics equation that defines the behavior of an induced electromagnetic field from the magnetic flux (change in a magnetic field) is Faraday's law of electromagnetic induction.
The process of electromagnetic induction works in reverse as well, so that a moving electrical charge generates a magnetic field.
The more generalized equation is one of Maxwell's equations, called the Maxwell-Faraday equation, which defines the relationship between changes in electrical fields and magnetic fields. It takes the form of:
∇×E = – ∂B / ∂t
