These demos are specially designed brushless DC electric motors. The moving parts have magnets in them and correspond to the rotor and flywheel of the motor. The base of the demo contains a battery, coil, steel core, and transistor. The moving rotor induces an electric current in the coil. This current is amplified and fed into an electromagnet which applies a torque to the magnetic rotor, which in this case has a magnet in each of the three arms.
NOTE: Be gentle with the rails of the demo. The tabs which connect the rails to the base are particularly fragile. The battery will last for 6 or 7 months of continuous use. The rails may have to be cleaned of dust periodically.
