Abstract
An inductor that is configured to store energy in a magnetic field includes a wire and a core. The wire is configured to deliver electrical current to the inductor to generate the magnetic field. The core is disposed radially about the wire. The core comprises magnetic particles that are suspended in a non-magnetic matrix. The magnetic particles are arranged such that a magnetic permeability of the core increases in a direction that extends radially outward from the wire along a cross-sectional area of the magnetic core from a first region that is adjacent to the wire to a second region that is adjacent to an outer periphery of the magnetic core.
