Material required : Old radio transformer, slot, iron core, copper disc.

Procedure :

  1. An old radio transformer can be made into a motor by cutting a slot in the iron core and arranging a copper disc to rotate in the slot.
  2. The disc will have to be spun by hand to get it rotating unless a starting coil is placed in a slot on one of the pole-pieces.
  3. This simple loop of wire also gives the motor much strength.
