A copper conductor (wire) with a diameter of 1 mm2 was coiled into a loop with a diameter of 10 cm and connected by a clamp. A small metal pot was filled with a little water (so not to overheat it) and was placed on the plate inside the copper circle. After switching the cooker on, thanks to the magnetic forces affecting the ring by the induced current, the ring took off. The experiment cannot last too long as the ring is extremely heated (if an insulated wire is used the insulation melts, therefore it is not wise to solder the ends of the loop). The pot serves as a ‘consumer’ for the energy as the protection does not switch the cooker off
