The simplest pulse motor ?

Just a MOSFET and a coil are the electornics to run this pulse motor. The rotor has 4x neodymium magnets, all facing North outward. Power is 3V. The motor will run from 3V to 12V+ and display no change at all in running speed. The circuit should be evident from the video. MOSFET is an IRF630. Wire colours don’t denote function, just what I had around.
