After bolting the work coil to the bus bars, it's covered by the blast shield. The energy discharge capacitors are then charged to the desired high voltage, storing a large amount of potential energy. The stored energy will be suddenly released into the work coil, creating an ultrastrong magnetic field inside the coil which radially crushes the coin. The interior of the blast shield is lined with steel, since Lexan alone cracks under repetitive bombardment by the copper fragments and the explosion's shockwave."
