Editing Radio-frequency induction (section)

: ''For the common use of RF induction process of heating a metal object by electromagnetic induction, see [[induction heating]]''

'''Radio-frequency induction''' ('''RF induction''') is the use of a [[radio frequency]] [[magnetic field]] to transfer [[energy]] by means of [[electromagnetic induction]] in the [[Near and far field|near field]]. A radio-frequency [[alternating current]] is passed through a coil of wire that acts as the [[transmitter]], and a second coil or conducting object, [[inductive coupling|magnetically coupled]] to the first coil, acts as the [[receiver (radio)|receiver]].
