Hans Christian oersted- Oersted's famous experiment showing that electricity and magnetism are linked, took place during a lecture on April 21, 1820, when Oersted was 42 years old. In the experiment he passed electric current through a wire, which caused a nearby magnetic compass needle to move

Faradays law-

1. 1.

PHYSICS

a law stating that when the magnetic flux linking a circuit changes, an electromotive force is induced in the circuit proportional to the rate of change of the flux linkage.

2. 2.

CHEMISTRY

a law stating that the amount of any substance deposited or liberated during electrolysis is proportional to the quantity of electric charge passed and to the equivalent weight of the substance.

Electromagnetic introduction- Electromagnetic or magnetic induction is the production of an electromotive force (i.e., voltage) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction
