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 parascience. There are frequent references to free energy and sometimes even links to esotericism.[3]

A hypothetical magnet motor works with permanent magnets in stator and rotor. By a special arrangement of the attracting and repelling poles, a rotational movement of the rotor is supposedly permanently maintained. Practical implementations fail because there is no substantial energy in magnets that could be employed for propulsion or to compensate for energy losses. The force between permanent magnets is conservative as the magnetic field follows a potential, so that there is no work done over a closed cycle. After a short amount of time, such a motor will stop moving and assume an equilibrium position.[1][3]
Rationalizations of proponents about the nature of the energy source vary. Some argue with magnetic force only, leaving questions of conservation of energy aside. Some argue that permanent magnets contain stored magnetic energy, which will be consumed by the motor. Such energy that exists is limited to the energy spent during the production of the magnet, which is rather small. Also, this would lead to a rapid reduction of the magnetization over time, which is not observed. Other rationalizations include references to so-called free energy and zero-point energy, without explaining how these energies are liberated. Others claim that their motors could possibly convert heat energy from the environment to mechanical motion (perpetual motion machine of the second kind).
In para-scientific circles, the magnet motor is still propagated and construction manuals are still distributed despite the lacking proof of function.[1] In the beginning of the 21st century, the idea of a magnet motor has been increasingly propagated on the internet and a number of fake videos showing pretended running magnet motors have appeared on online video-sharing platforms.[11] Addressing the question, why the magnet motor is still not adopted by the industry, despite its supposedly great potential, conspiracy theories are put forward: Magnet motors would provide free energy for everyone, harm the existing energy industry, and would thus be suppressed.
