Question

What is electromagnetic induction?

Answer 1

electromagnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field

Answer 2

hey frnd...
Whenever an electric current flows through a conductor, a magnetic field is immediately brought into existence in the space surrounding the conductor.
It can be said that when electrons are in motion, they produce a magnetic field. The converse is also true i.e. when a magnetic field embracing a conductor moves relative to the conductor, it produce a flow of electrons in the conductor.
This phenomenon whereby an e.m.f. and hence current is induced in any conductor which is cut across or is cut by a magnetic flux is known as
electromagnetic induction .
