   Levitation melting is a metallurgical technique that uses electromagnetic forces to suspend and melt materials, typically within a conical helical inductor, without any physical contact with crucibles.

     @wonderofscience Does the material levitated have to be ferromagnetic?

     @wonderofscience #alt4you A small metal cylinder is placed into the center of a copper winding. The cylinder hovers in the center of the coil, and after a period of time begins to spin and incandescence red hot, elongating as it melts. It eventually plops onto the table below when it becomes liquid. The solid remains are then removed from the table.
