How do electric motors work?
|
|
An electric motor is made of a coil of wire inside a magnet. The coil is free to turn. When an electric current flows through the coil, it magnetises the coil. This magnetic field pushes against the magnetic field produced by the surrounding magnet, and this makes the coil spin.
