Claim 11:
12. An electromagnet comprising,
a plurality of flat spiral electromagnetic coils, wherein each spiral electromagnetic coil of said plurality of flat spiral electromagnetic coils has a plurality of turns, wherein the electromagnetic coils of said plurality of flat spiral electromagnetic coils are comprised of an electrical conductor,
each said flat spiral electromagnetic coil stacked on top of each other, to form a stack of flat spiral electromagnetic coils,
wherein each said flat spiral electromagnetic coil is approximately aligned and spaced apart at a predetermined distance between neighboring coils within the stack,
wherein the flat spiral turns of each said flat spiral electromagnetic coil within said stack are uncompressed,
said stack of flat spiral electromagnetic coils having wire ends that are either joined together or continuous with predetermined clockwise or counter-clockwise winding,
a magnetic composite, said magnetic composite being comprised of a magnetically isotropic material,
said stacked flat spiral electromagnetic coils encased or embedded in said magnetic composite, wherein said wire ends are exposed.
