Design and calculation of induction-heating coils

THROUGH the years the author has had considerable experience with induction-heating calculating methods and has studied the reaction of others confronted with the problem of designing coils and predicting performance. It is a difficult job at best when one considers the great variety of materials heated and the almost limitless variety of shapes encountered. It is little wonder that the average engineer resists using calculating methods as much as he does. In an effort to develop a more or less standard calculating procedure for internal use in his company, the author arrived at the plan described in this paper.
