1. An electromagnetic core assembly, comprising:
a U-shaped annular magnetically conductive electrically insulating (MCEI) mesh housing comprising opposed vertical sides joined by a bottom side and one or more annular bumper stripes circumscribing at least one of the opposed vertical sides;
the U-shaped MCEI annular mesh housing defining an annular open channel bounded by the opposed vertical sides and bottom side;
an annular U-shaped MCEI core comprising opposed vertical sides joined by a bottom side disposed within the annular open channel, and
an annular electrical conductor embedded within the U-shaped MCEI core wherein the MCEI core comprises annular reinforcement rods embedded within the MCEI core.
