Method for reducing core losses in silicon steels and other similar materials having antiparallel domain wall structures by applying high frequency (e.g., 400-800 Hz.) oscillatory wave energy to a winding surrounding a transformer or other device using the steel or the like as a core material. Following a power surge experienced by the transformer or other electrical apparatus, the number of domain walls is reduced, increasing core losses. By applying a pulse of high frequency wave energy following the surge and at a flux density preferably in excess of 15,000 gauss, the number of domain walls can again be increased to reduce core losses.
