Numerical simulations have been performed on directional solidification furnace with magnetic induction coils. The rotating magnetic field was applied by using magnetic coils to influence the melt stirring and melt-crystal interface shape. The velocity of the melt flow and distribution of the stream function were improved by placing the magnetic induction coils inside as compared to outside of the insulation which may be used to control the melt flow patterns. The value of velocity field in silicon melt flow is 2E-5 m/s when the magnetic coil is placed inside the insulation. The value of velocity field in silicon melt flow is 2E-4m/s when the magnetic coil is placed outside the insulation. And, the resistive heaters are replaced by the inductive heaters to produce the heat and magnetic fields simultaneously. The results are compared with the magnetic coils placed inside the insulation..
