High Frequency Eddy Current Heating principle - Advantages

High Frequency Eddy Current Heating. When current-carrying conductor is wound on the soft iron piece then a circulating current is produced in it by electromagnetic induction.Its shape is just like an eddy, so it is called as eddy current.. This eddy current produces loss that is called as eddy current loss.This loss produces heat in the soft iron piece and can be used to heat the material.
