    Coil is rotated by an outside source of mechanical energy Examples: Steam, wind, water As the coil turns in the magnetic field, electric current flows through the wire When the coil turns so that the ends move past opposite ends of the magnet: The current reverses direction The current changes direction twice with each revolution A generator that is used in a car is known as an alternator
