[Diato556] made a really cool single-phase induction motor with parts mounted on Duplo blocks. He has posted an Instructable where he uses these modular parts to demonstrate the motor and the principles of induction as described after the jump. Alternator [Diato556] starts with an AC generator, a tiny alternator made with the coil from a relay and the magnet from a bicycle dynamo. He rotates the magnet on a spit in front of the relay coil, producing an induced current that lights an LED connected to the relay. Rotating magnetic field Next up is a rotating magnetic field demonstration. Using the same rotisserie magnet, he induces a current in a rotor made from a small aluminium cylinder. The cylinder pivots against a nail and induced current causes the rotor to spin. Induction motor The induction motor builds from previous experiment. Instead of the magnet, the two coils in...
