# A report on Faraday's law of induction, Electromagnetic induction and Transformer

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.

- Faraday's law of inductionIt is the fundamental operating principle of transformers, inductors, and many types of electrical motors, generators and solenoids.

- Faraday's law of inductionMichael 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 inductionFaraday's law of induction, discovered in 1831, describes the induced voltage effect in any coil due to a changing magnetic flux encircled by the coil.

- TransformerElectromagnetic induction has found many applications, including electrical components such as inductors and transformers, and devices such as electric motors and generators.

- Electromagnetic inductionElectromagnetic induction, the principle of the operation of the transformer, was discovered independently by Michael Faraday in 1831 and Joseph Henry in 1832.

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

AC has come to dominate due to the ability of AC to be easily transformed to and from very high voltages to permit low losses over large distances.

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

In electromagnetic induction, emf can be defined around a closed loop of conductor as the electromagnetic work that would be done on an electric charge (an electron in this instance) if it travels once around the loop.

Devices that can provide emf include electrochemical cells, thermoelectric devices, solar cells, photodiodes, electrical generators, transformers and even Van de Graaff generators.

The general principle governing the emf in such electrical machines is Faraday's law of induction.

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

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.

Near the entrance to its dining hall is a bronze casting, which depicts the symbol of an electrical transformer, and inside there hangs a portrait, both in Faraday's honour.
