A continuous wire that includes a wound inductance from a first yarn material formed of filaments or nanotubes, the first yarn being doped with or including a first material that causes it to be electrically conductive and a second yarn formed of material filaments or nanotubes that is electrically insulating and may include magnetic particles wound with the first yarn in bifilar fashion or both yarns wrapped in a bifilar fashion around an insulating core yarn which may include magnetic particles to increase the inductance of the wire. The doping and electrical conductance of the yarns can be varied along the length of the wire to integrate sections of lumped electrical conductance and inductance.
