Abstract
Ferromagnetic cores made from amorphous glasses and methods of forming ferromagnetic cores from metallic glasses are provided. The method forms a magnetic core from a section of a series of concentrically nested ferromagnetic tubes formed of an amorphous metallic material having a Curie-point temperature above room temperature and demonstrating soft ferromagnetic properties, thereby simplifying the manufacturing process and improving the electrical and mechanical performance of the core itself.
