Numerical simulation studies on the removal of contaminants in the conducting fluid using the electromagnetophoresis are presented. Applying the high-frequency electromagnetic fieled to the conducting liquid, two vortices are induced in a cylindrical pipe. The upstream vortex conveys the contaminants from the center to near the wall. In the region near the surface opposite to the induction coil high Lorentz force acting on the liquid results in the electromagnetophoresis of contaminants toward the wall. With the increase in the current of coil the removal efficiency increases. There exists the optimum frequency to the efficiency because of the compensation of the electromagnetic coupling and the skin effect. The removal efficiency also increases with the coil width.
