Experiment was carried out for Czochralski convection of liquid metal under the rotatio nal and horizontal magnetic field. A gallium melt in the crucible was heated at the sidewall and cooled at the upper rotating rod. This crucible was set into the horizontal and the rotati onal magnetic field and the temperature in the melt was measured for several values of the rotational rates of cooling rod and the rotational frequency of magnetic field. The melt temperature was fluctuate and the amplitude and oscillation period were changed at each cases.
