A generator. Essentially, a generator is a magnet rotating inside a coil of wires. The magnet induces electrical current in the coil of wires.

ac (alternating current) differs from dc (direct current) by travelling in two directions. ac goes back and forth (alternating directions) instead of only one way (direct). the electricity is produced by a magnet spinning in close proximity to a metal or a metal spinning around a magnet.

consider a magnet is producing constant flux.now when we rotate a conductor(conductor in the sense a turn consisting of two conductors connrcted at one side) in the flux current is produced according to electromagnetic principle.this current produced will be varying sinusoidally when we complete one rotation.this is called ac(alternating current)
