Numerical computations were carried out for the concentration in the Czochralski bulk flow under a horizontal rotating magnetic field. The velocity in a vertical cross section was decreased under the rotational magnetic field compared to the horizontal static magnetic field for the same magnetic induction. The concentration difference at the crystal-melt interface was decreased in increasing the magnetic induction under the horizontal and rotational magnetic field. Under the rotational magnetic field, the concentration difference was increased in increasing the rotational rates of magnetic field.
