ABSTRACT:
An induction coil for inductively heating electrically conductive materials includes a plurality of individual coil turns, each turn lying in a plane substantially perpendicular to a longitudinal axis of the coil and comprising an electrical conductor formed into an annulus. The conductor has first and second terminals for connecting the turn to an electrical circuit. The first and second terminals are adjacent each other at a preselected circumferential position on the annulus and are physically and electrically isolated from each other. The first terminal of one turn is located adjacent and electrically connected to the second terminal of an adjacent turn. The first terminal of a selected one of the plurality of turns forms a first coil terminal and the second terminal of a different selected one of the plurality of turns forms a second coil terminal.
