Abstract
An improved conductor for an inductor device of the type having varying current carrying requirements along the length of the conductor, the improvement comprising having the conductor contoured such that the cross sectional area of the conductor varies substantially directly as the current carrying requirements of the conductor vary. In one embodiment, a coil for a variable transformer is cut from a cylinder of conductor material by numerically controlled machining, producing a contoured conductor and eliminating the requirement for coiling or winding of the conductor.
