Electic generating stations covert mechanical enery into electrical energy.An extrnal energy
source is used to push on the blades of a fan-like device called a turbine,causing it to turn.
The turbine is connected to the movable parts of another device called generator.Inside the
generator,a coil of wire is held between the two poles of a magnet.The wire is made of copper
because copper is a good conductor of electricity.When the turbine rotates, the coil of wire
in the generator also rotates.Since the moving coil is held near a magnet,electrons begin to
flow in the wire.These electrons eventually move in transmission lines to the electrical outlets
in your home.
