ABSTRACT:
One of the key features of the present invention is the use of a electrical conduit arrangement that allows for the tailoring of the magnetic field so as to provide for the greater amount of force to be brought to bear generally in the center of the work force area. The present invention provides for such capability by providing for a single central current conduit for forming longitudinally extending work pieces. The present invention also provides for the splitting, and/or direction (or curvature) reversal, of the electrical current pulse one or more times to likewise tailor the magnetic field of the work-coil or forming actuator.
