Abstract

Surface oscillation behavior of electromagnetically levitated molten copper was investigated under a static magnetic field in the range from 0 T to 1.0 T. Although the frequencies of m = 0 and ± 1 oscillations were almost kept constant up to 0.2 T, they became negligibly small above 0.2 T. The frequency of m = ± 2 oscillation gradually decreased as the static magnetic was increased up to 1.0 T. This behavior was basically interpreted in the following way, i.e., the Lorentz force acting on the copper droplet causes a resistive force to the surface oscillation, which leads to decreases in frequencies of surface oscillation.
