Half Cycle Magnetizer

I would like to find a schematic for a half cycle magnetizer. The one that I have runs on three phases but I need one that runs off of the 120 volt line at 60 cycles. The working load that I need is about 5" x 5" x 4" or bigger. The specs for the output coil and the fast solid-state switch are most important. I realize that the magnetizer must be enclosed with non-magnetic material and probably uses a big heatsink.
