Summary:The separation method using electromagnetic force is receiving particular attention as an elimination method of inclusions in molten metal. In this study, low-melting metal is used as a model metal and separation control by electromagnetic force is discussed. The motion of a levitated insulated lead ball in convective molten metal was studied by calculation and through experimentation. It was found that the force by convection is weaker than the electromagnetic force under experimental conditions. It was successfully demonstrated that the motion of the insulated lead balls injected into the molten metal could be controlled using an electromagnetic field.
