Magnet Motors and Air Coils from Speakers

This video shows some of my magnet motors driven by Air Coils harvested from old speakers. The motors start easier and run faster than when driven by the sewing bobbin 30 ga magnet wire coil. The circuit is from SMartCreations and I suggest you visit his channel for more information. The hematite sphere is one of my favorites as it takes an insane amount of time to spin down. Hope you enjoy this video and possibly got some ideas for building your own magnet motor.
