DEFINITION

Classification: 117/51

Electromagnetic induction:

(under subclass 50) Subject matter in which the energy for liquefying is supplied by electric or magnetic induction phenomenon by the influence of a neighboring electric or magnetic field (e.g., radio frequency waves).

(1) Note. Heating by radiation or by electron beam is

placed above in subclass 50, unless accompanied by application of a source of electromagnetic induction energy.
