Abstract
A magnetic implement has a gap size ranging from about 1 to about 20 mm. The implement comprises a magnetic core composed of an amorphous Fe-based alloy. A physical gap is disposed in the core's magnetic path. The alloy has an amorphous structure; is based on the components: (Fe—Ni—Co)—(B—Si—C). The sum of its Fe+Ni+Co content is in the range of 65–85 atom percent. Advantageously, the core exhibits an overall magnetic permeability ranging from about 40 to about 200 and enhanced magnetic performance.
