An electrical generator is a machine wich converts mechanical energy into electrical energy..
This energy conversion is based on the principle of the production of dynamically induced emf.i.e whenever a conductor cuts magnetic flux,dynamically induced emf is induced in it according to faradays laws of electromagnetic induction.This emf causes a cuent to flow if the conductor is closed.
