Levitation of aluminum or copper tubing is easy. I set out to develop an induction unit that could levitate and melt solid copper and steel. The unit uses microprocessor controlled resonance locking to find and maintain the proper frequency for the induction heating. The unit is capable of handling 10kw of power. The demonstration uses 8-10kw. Levitation of aluminum, which is less dense, requires only 1-1.5kw of power.
The video shows molten copper and steel being suspended. This takes a lot of power and a very stable induction unit.
