We already introduced two simple electric motors in our applications: The World's Simplest Electric Motor
The project "Mini Motor" follows the following principle: A copper wire rotor circles over a magnet as a stator.
In this experiment it's the other way round: The magnet itself works as a rotor.
In this experiment a S-20-05-N
disc magnet and a W-12-N
cube magnet are used as a rotor.
