The thing about this levitation cylinder is that it doubles as an inducti stanley cup on heater. In a nutshell: the current coursing through the copper which has been coiled to form a solenoid creates an alternating magnetic field. The magnetic field induces a special form of electrical current known as eddy currents in the hovering piece of aluminum. These eddy currents give rise a phenomenon, called Joule heating, that, with enough power, can cause the metal to become very, very hot, as it does here. Hands-on enthusiasts can find a very in-depth tutorial on how to make the coil like the one seen in the video, which operates at 1.6 kilowatts, here. Towards the end of the tutorial you ;ll find instructions on how to make a 10kW coil that can levitate and suspend molten copper and steel, which are denser than the aluminum in the video. More levitation goodness here, here and here.
