Ball Bearing Motor - How to Make/How it Works

A ball bearing motor, showing how to make one and how it works. I use roller bearings from which I've removed the grease and a piece of wood for the flywheel. For the low voltage, high current I use a microwave oven transformer. This is sometimes also called a Marinov motor.

WARNING: This ball bearing motor involves lethal electrical current
so replicate this at your own risk. Do not use it for a science fair
project as it is dangerous to leave unattended.
Some alternatives to the microwave oven transformer are:
car battery
soldering gun with the tip removed (not sure if this has been tried)
