  2. Introduction • Electromagnetic induction: is the production of voltage across a conductor moving through a magnetic field . • Michael faraday: is generally credited with the discovery of the induction incident in 1831 though it may have been anticipated by the work of Francesco Zantedeschi in 1829.

  3. Electrical generator • An electric generator is a device that converts M.E to electrical energy. • Ageneratorforces 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. The source of M.E may be a turbine (steam engine).

  5. Transformers • A transformer is a static device that transfers electrical energy from one circuit to another through the transformer's coils. • A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic field through the secondary winding.
