Abstract: Method precisely, quickly controls flow of molten metal to metal-casting apparatus by pumping, braking or throttling. The Faraday-Ampére principle of current flow in a unidirectional magnetic field is employed. Permanent magnets comprising neodymium or similar high-energy, rare-earth materials provide “reach-out” magnetism. These neo-magnets, usually shown as cubes, are arranged in various powerful configurations driving intense unidirectional magnetic field B across a non-magnetic gap many times larger than economically feasible otherwise. This gap accommodates a conduit for pressurizing and moving a flow of molten metal. In making multiple identical castings, a controlled, intermittent, predetermined flow of molten metal is fed to a series of identical individual molds. The invention obviates needs for operating metallurgical valves or expensive tilting mechanisms for metallurgical furnaces.
