1. A nanomagnetic inductor core comprising:
a porous, electrically-insulating template having high-permeability material in the pores thereof to constitute elongated nanowires, wherein the elongated nanowires are segmented along their axial direction; and
a segment of dielectric material interposed between adjacent segments of the high-permeability material along the axial direction of the nanowire.
