Abstract: An EMP apparatus includes first and second opposed field shaper segments. The field shaper segments include opposed working portions. First and second coil segments respectively support the first and second opposed field shaper segments. The coil segments are electrically operable and in eddy current contact with the field shaper segments. Insulators are disposed between the field shaper segments and the coil segments. A frame moveably supports the coil segments for movement between open and closed positions of the coil segments. Metal stock can be disposed between the shaper segment working portions by opening the shaper and coil segments.
