THE ELECTRIC MOTOR.

An electric motor consists of a coil of wire between two magnets.

Electric motors electrical energy into energy, that is, in movement.

Many everyday appliances have an electric motor inside which uses electromagnetism to work, like blenders, toasters, or hairdryers.

THE ELECTRIC GENERATORS.

An electric generator tranforms into an electric , like a .

A dynamo uses a and a conductive coil of to produce an electric current and make a bycicle´s work. In the dynamo the magnet move but the coil does not.

Power stationss use electricity generators similar to dynamos, but much , because they need to produce much more electricity.
