DEFINITION

Classification: 264/486

Induction heating:

(under subclass 405) Processes wherein the material is subjected to induction heat.

(1) Note. Induction heat is considered to be heating of a nominally electrical conducting material by eddy currents induced by a varying electromagnetic field. When an alternating current flows through a coil surrounding or adjacent a nominally conducting material, eddy currents will be induced therein, causing said material to be heated.
