Abstract
A magnetic induction pump for pumping molten metal. The pump includes a motor and a shaft operatively connected to the motor. The pump further includes at least one bipolar permanent magnet operatively connected to the shaft and a conduit for the passage of molten metal. The motor rotates the shaft and magnet about the conduit inducing eddy currents in the molten metal in the conduit which react with the moving magnetic field to produce force to pump the metal through the conduit with the metal coming into contact with only an interior surface of the conduit.
