A magnet motor or magnetic motor is a type of perpetual motion machine, which is intended to generate a rotation by means of permanent magnets in stator and rotor without external energy supply. Such a motor is theoretically as well as practically not realizable.[1][2] The idea of functioning magnetic motors has been promoted by various hobbyists. It can be regarded as pseudoscience. There are frequent references to free energy and sometimes even links to esotericism.[3]
Magnet motors are not to be confused with the commonly used permanent magnet motors, which are powered from an external electrical energy supply.
