We already introduced two simple electric motors in our customer projects: The World's Simplest Electric Motor
The 'Mini Motor' project is based on the principle of a copper wire rotor turning over a magnet as a stator. In this experiment, it is the other way round: the magnet itself acts as the rotor. In this experiment a S-20-05-N disc magnet and a W-12-N cube magnet are used as a rotor.
