SIMPLEST DC MOTOR




   

PARTS

Copper wire
Wooden base
One or two magnets
Battery case with 4 AA cells


     This motor is based on the  coil being turned on and off by an insulation on the shaft itself. On one side of the shaft touching the holder, all the varnish is removed. On the other end, only half side is removed. So the electric flow gets interrupted to the coil.
