Analysis of Heat Production in Induction Heating Irons

The eddy currents in heating irons induced from ferrite-core induction coils are calculated using a theoretical approach and the results are compared with experimental data. Optimizations of components and materials for constructing the induction head are investigated to develop new type induction heating irons. Formulations in our theory are based on the magneto-resistance calculations. The self- and mutual- inductances are estimated precisely using these magneto-resistances. Induction heating phenomena are analyzed theoretically using the eddy currents. Finally, the heated iron is shown in good agreement of parameters.
