This simple experiment demonstrates the principle of induction motors. Above a horseshoe magnet, an aluminium disc can rotate around a vertical axis. Rotation of the magnet leads to a rotating magnetic field.
00:24
This induces eddy currents in the disc and these experience forces in the magnetic field. They cause the disc to rotate as can be seen with a little flag attached to the disc.
