ABSTRACT:
A method of stress-relief annealing a magnetic core constructed of magnetic, metallic strip material, with at least a portion of the strip material being amorphous, wherein the strip material has major plane surfaces which define first exposed surfaces of the magnetic core, and lateral edges which collectively define second exposed surfaces of the magnetic core. The method includes the step of thermally insulating the first exposed surfaces of the magnetic core, and the step of heating the magnetic core via the second exposed surfaces.
