A new type of magnetohydrodynamic calculation method is proposed to evaluate the electromagnetic sensing process, in which fluid dynamics makes much influence on the electromagnetic field. First, multi-phase flow of molten steel and slag are momentarily performed in fluid calculation in the proposed method. Second, conditions of multi-phase flow are momentarily performed in electromagnetic calculation. Last, secondary voltages are momentarily calculated. It is able to observe internal state of multi-phase flow of molten steel and slag by fluid calculation. It was able to understand the relation between slag detection process and sensor output by magnetohydrodynamic calculation.
