when a magnetic field embracing a conductor moves relative to the conductor it produces a flow electrons in the conductor. This phenomenon whereby an e.m.f and current is induced in any conductor which cut across or cut by a magnetic flux is known as ELECTROMAGNETIC INDUCTION.
HISTORY OF MAGNETIC INDUCTION:
After discovery of that electric
current produces magnetic field, scientist are trying to search for the
converse phenomenon from about 1821. The problem they put themselves was - how
to convert Magnetism to Electricity. It is recorded that Michael Faraday ( A
English Physicist and Chemist) was in the habit of walking about with magnets
in his pocket so as constantly remind him of the problem to solve.
After Nine year of continuous full
phase research and experiment he succeeded in the producing electricity by
converting magnetism. In 1831 he formulated basic laws underlying the
phenomenon of electromagnetic induction, after that these know by Faraday's
Law. Motor, Generator, Transformer, Induction cooker and many other apparatus
based on this law.
