Kids get to learn about principles of electricity through building their very own electric generator. Just turn the handle to make the pullies spin an electric motor and turn on a light.
The connecting wheels of the large and small transmission wheels increase the engine speed. There are magnets and copper coils inside the generator. The copper coil rotates to cut the magnetic induction line motion, thereby generating an induced current. Light up the small lamp beads by boosting the voltage through the booster board.
