How induction is used to heat metals

Induction, or electromagnetic induction, refers to the generation of electrical fields by the alteration of the magnetic flux density. In induction heating, this is achieved using an inductor through which alternating current flows, thus generating an alternating magnetic field.

Induction – generating heat directly in the workpiece

Induction results from the interplay of magnetism and electrical voltage, of magnetic and electrical fields.

Induction heating involves the induction of an electrical field, and thereby eddy currents, in the material being heated. These eddy currents generate the heat in the material itself. The depth of penetration depends on the frequency of the alternating current applied on the inductor. As a basic rule, the higher the frequency, the lower the induction of eddy currents in the material.
eldec's generators and custom-made inductors ensure high precision control of the energy applied to the material being heated.
