Abstract

A magnetic component having a unitary structure, a transverse flux electric machine having the magnetic component, and a method of making the magnetic component are disclosed. The unitary structure of the magnetic component includes a magnetic region and a non-magnetic region. The magnetic region includes a magnetic phase and an electrically insulating phase. The non-magnetic region includes a non-magnetic phase. The magnetic phase includes a metallic material and the non-magnetic phase includes a nitrogenated metallic material formed by a controlled nitrogenation of the metallic material.
