Electromagnetic induction and electricity generation

Michael Faraday

For everyone

In 1831 Faraday discovered that a changing magnetic field produces an electric current in a wire. Almost every power station today generates electricity on this principle by turning turbines. Transformers and electric motors rest on the same principle.

For specialists

Faraday worked with two coils wound on an iron ring and observed a momentary current in the secondary circuit when the primary was switched on or off. Faraday's law is written ε = −dΦ_B/dt; Lenz's law gives the direction of the induced current. Maxwell incorporated the law into his field equations.

Experiment

Faraday observed the galvanometer deflect when a magnet was moved in and out of a coil, and no current when the magnet was at rest.[1]
