To obtain a high-response electromagnetic sensor, the mechanism of shield effect is made clear, where the copper shield is arranged between the primary coil and the secondary coil. To estimate it, a new index is introduced as a ratio of effective magnetic flux among the magnetic flux linked to the secondary coil. According to the numerical calculation, the insertion of the copper shield makes the responsibility index increase. Since the effective flux ratio increases by inserting the copper shield, the magnetic flux is considered to be used effectively to detect the molten steel among the secondary voltage.
