Abstract

The authors describe the use of a magnetic-field computation software (based on the boundary-element method) in the determination of eddy currents in very thin plates. The thin character of the plate and its magnetic and conducting properties are taken into account by using special integration methods. The technique is applied to an induction oven (the aspect ratio of the plate is 1/500). It is noted that energy conservation seems to be a good indicator of the solution quality in integral methods. The adaptive integration method gives the best results
