Radio frequency induction

Helping orphans the way you would do it
Radio frequency induction or RF induction is an electrical phenomenon in which an electromagnetic wave passing through a conductor causes electric current to flow through it. It is a special case of electromagnetic induction.

A common use of RF induction is induction heating (also called eddy-current heating), a method of rapidly heating a conducting material. The skull crucible, a specialized device for growing cubic zirconia crystals, uses this effect.
