Electromagnetic induction is the production of voltage across a conductor moving through a

magnetic field. It underlies the operation of generators, all electric motors, transformers,

induction motors, synchronous motors, solenoids, and most other electrical machines.

Michael Faraday is generally credited with the discovery of the induction phenomenon in 1831

though it may have been anticipated by the work of Francesco Zantedeschi in 1829. Around 1830 to 1832 Joseph Henry made a similar discovery,

but did not publish his findings until later.

An electric motor converts electrical energy into mechanical energy. Most electric motors operate

through interacting magnetic fields and current-carrying conductors to generate force,

although electrostatic motors use electrostatic forces. The reverse process, producing electrical energy from mechanical energy, is done by generators such as an alternator or a dynamo. Many types of electric motors

can be run as generators, and vice versa. For example a starter/generator for a gas turbine, or

traction motors used on vehicles, often perform both tasks. Electric motors and generators are commonly

referred to as electric machines.

electric generator is a device that converts mechanical energy to

electrical energy. The reverse conversion of electrical energy into mechanical energy is done by a motor; motors and generators have many similarities. A generator forces

electrons in the windings to flow through the external electrical circuit. It is

somewhat analogous to a water pump, which creates a flow of water but does not

create the water inside.
