摘    要：对影响液态金属所受电磁力大小的因素进行了研究，对电磁力作用下的导电流体中的非金属颗粒的迁移速度进行了测定。结果表明：金属液回路的几何尺寸、行波磁场发生器的气隙大小以及发生器中通过的电流等对电磁力参数产生很大的影响；行波磁场能使微细非金属夹杂物（5~100μm）的迁移速率成倍提高。

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.
