Generator

an electrical generator is a machine which convert mechanical energy (or power) into electrical energy (or power)

principle:

it is based on the principle of production of dynamically (or motionally) induce e.m.f (electromotive force). whenever a conductor cut magnetic flux,dynamically induce e.m.f. is produce in it accordin to faraday's lows of electromagnetic induction. this e.m.f causes a current to flow if the conductor circuit is closed.

this is a ac generator picture.
