Electromagnetic device and system for pumping, circulating or transferring non-ferrous molten metal

An electromagnetic device for pumping, circulating or transferring non-ferrous molten metal, the electromagnetic device comprising:

• a duct made of a refractory material, the duct having a first aperture at a first end of the duct and a second aperture at a second end of the duct, the duct configured to convey a body of non-ferrous molten metal between the first and second apertures, the duct configured to enclose the body of non-ferrous molten metal between the first and second apertures, and the duct having opposing first and second external side surfaces;
• a first inductor assembly extending adjacent to the first side surface, wherein the first inductor assembly comprises a plurality of inductors arranged along a length of the duct adjacent to the first side surface;
• and
• an electronic circuit configured to generate direct current pulses that energise each inductor of the plurality of inductors in a sequence, so as to generate a moving magnetic field within the body of non-ferrous molten metal which propels the body of non-ferrous molten metal along the duct.
