Radio-frequency induction

From Free net encyclopedia

Radio-frequency induction or RF induction is the use of a radio frequency magnetic field to transfer energy by means of electromagnetic induction. A radio-frequency alternating current is passed through a coil of wire that acts as the transmitter, and a second coil or conducting object, magnetically coupled to the first coil, acts as the receiver.

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.Template:Physics-stub
