An electrical generator is a device that produces electrical energy from a mechanical energy source using electromagnetic induction. The process is known as electricity generation.

Historic developments


Before the connection between magnetism and electricity was discovered, generators used electrostatic principles. The Wimshurst machine used electrostatic induction or "influence". The Van de Graaff generator uses either of two mechanisms:
  • Charge transferred from a high-voltage electrode
  • Charge created by the triboelectric effect using the separation of two insulators (the belt leaving the lower pulley)
Electrostatic generators are inefficient and are useful only for scientific experiments requiring high voltages.
