Abstract
A method of reducing core losses in a magnetic core characterized by the steps of winding a strip of a previously annealed amorphous magnetic alloy strip into a magnetic core; applying a primary winding onto the magnetic core to establish an AC exciting field in the core; applying a secondary winding onto the core; and applying a DC or a low frequency AC magnetic field to the core at an angle that is non-coincident to the AC exciting field to effect reduced high frequency core losses.
