ABSTRACT:
It has been discovered that a series of grooves in the surface of amorphous magnetic alloy strip can significantly reduce core losses if the grooves are generally transverse to the direction of magnetization. The grooves are between 0.1 and 10.0 of the strip thickness in depth and are preferably on both sides of the strip and spaced about 0.02-2 centimeters apart.
