1. An apparatus, comprising:
a toroid shaped inductor, said toroid shaped inductor comprising:
an inductor core, said inductor core comprising:
a plurality of coated particles comprising an average particle size of less than one hundred micrometers, each of a majority of said coated particles comprising:
at least three layers;
a first set of alternating substantially magnetic layers; and
a second set of alternating substantially non-magnetic layers,
an inductor winding about at least a section of said inductor core, said winding configured to transmit a current of at least fifty amperes,
said toroid shaped inductor configured to carry a magnetic field of less than 7,000 Gauss at an absolute Oersted value of at least 200,
said coated particles about evenly distributed in at least a portion of said inductor core; and
a cooling jacket, said cooling jacket comprising at least two sections, wherein said at least two sections of said cooling jacket join to encase said toroid shaped inductor.
