ABSTRACT ANNEALING OF THERMALLY INSULATED CORE A magnetic core is wound from amorphous metal ribbon to form an outside surface, an inside surface and top and bottom surfaces. The core is annealed by being heated to and held at a first temperature for a preselected period of time and then cooled to a second temperature. Insulation applied to the inside and outside surfaces of the core prior to the heating step, substantially reduces the time period required for the anneal and markedly improves the properties of the core.
