Michael Faraday was an English physicist and chemist, the founder of the theory of the electromagnetic field.

Here are some of his discoveries:

In 1831, he discovered the phenomenon of electromagnetic induction, which underlies the operation of all direct and alternating current generators.

In 1833, he discovered the laws of electrolysis (Faraday's laws).

In 1845, he discovered the phenomenon of rotation of the plane of polarization of light in a magnetic field (the Faraday effect).

Introduced a number of concepts into science - cathode, anode, ions, electrolysis, electrodes.

Invented the voltmeter in 1833.

In 1845, he first used the term "magnetic field".
