Magnetic induction - the levitating bbq

At the Palais de la Decouverte in Paris, a 1kg aluminium plate is levitated above a large coil of wire that is being supplied with 800A of alternating current at 900Hz.

Note the flare of the globes on the lamp when he moves it into the magnetic field and the steam coming off the surface - it’s also humming with the frequency of the alternating current. If you have time I recommend watching the video - it is very entertaining.
