In continuous casting, to provide products with excellent quality with high productivity. A molten metal from a melting furnace is stirred and driven by a Lorentz force due to crossing of magnetic lines of force from a magnet and direct current and sent to a mold while improving the quality of the molten metal, or a molten metal immediately before solidification in the mold by the Lorentz force to equalize the temperature of the molten metal immediately before solidification in the mold. As a result, finally a high quality product can be obtained, and the performance of the magnet can be maintained by cooling the magnet.
