Abstract:The factors which affect the magnitude of the el ectromagnetic force imposed on the molten metal were investigated, and the remov al rate of the non-metallic particles immersed in the conductive liquid was det ermined. It was shown that the geometric size of the loop forms by the molten me tal, the size of the gap of the magnetic generator and the electric current in t he generator affect the magnitude of the electromagnetic force greatly. The remo val rate of the micro non-metallic particles (5~100 μm) in the liqui d metal can be improved by times compared the case without EM force.
Key words: metal purifying；electromagnetic force；travelling mag netic field
