Question

What is electro magnetic induction.?​

Answer 1

Answer:-

Then by either moving the wire or changing the magnetic field we can induce a voltage and current within the coil and this process is known as Electromagnetic Induction and is the basic principle of operation of transformers, motors and generators.

Electromagnetic Induction was first discovered way back in the 1830’s by Michael Faraday. Faraday noticed that when he moved a permanent magnet in and out of a coil or a single loop of wire it induced an ElectroMotive Force or emf, in other words a Voltage, and therefore a current was produced.

HELLO DEAR FRIEND

$\large \bf \it \underline \red{electromagnetic \: \: \: induction.}$

$\underline{Electromagnetic \: \: \: Induction}$ is a current produced because of voltage production (electromotive force) due to a changing magnetic field. This either happens when a conductor is placed in a moving magnetic field (when using AC power source) or when a conductor is constantly moving in a stationary magnetic field.

This phenomenon was discovered by Michael Faraday in 1830s . Figure below shows the setup for electromagnetic induction.
