Abstract

A magnetic core including (i) a first magnetic material having a first magnetic permeability to substantially provide a core body of the magnetic core, and (ii) a second magnetic material having a substantially triangular structure positioned in a corner region of the core body. The corner region is defined by a region of the core body where a first portion of the core body coincides with a second portion of the core body in a manner that is substantially perpendicular. The second magnetic material is used to substantially evenly distribute magnetic flux in the magnetic core, and the second magnetic material has a second magnetic permeability that is lower than the first magnetic permeability.
