Faraday's law of induction (briefly, Faraday's law) is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (emf)—a phenomenon known as electromagnetic induction.

His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis.

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.

- Electromagnetic induction

Electromagnetic induction was discovered independently by Michael Faraday in 1831 and Joseph Henry in 1832.

His demonstrations established that a changing magnetic field produces an electric field; this relation was modelled mathematically by James Clerk Maxwell as Faraday's law, which subsequently became one of the four Maxwell equations, and which have in turn evolved into the generalization known today as field theory.

The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday.

The principle, later called Faraday's law, is that an electromotive force is generated in an electrical conductor which encircles a varying magnetic flux.

Alternating current generating systems were known in simple forms from Michael Faraday's original discovery of the magnetic induction of electric current.
