Referring to the previous studies on the first model of the induction stirrer of laboratory scale (455W), the second one in a semi-industrial scale (40k VA) was constructed in March, 1952. It was designed to operate on 3 phases, 50 cycles per second at 220 volts for 100kg basic electric arc furnace in our laboratory. The distribution of flux density over the stirrer was measured with respect to the vertical and horizontal components. 18-8 stainless steel and brass as the construction material of nonmagnetic furnace shell were compared with respect to the following subjects : (1) distribution of flux densities in the inside of the furnace shell, (2) stirring speed of thin mercury pool at the similar position of melt, (3) heat generation of the furnace shell by the moving electromagnetic field induced by the stirrer.
