A nozzle input control system using an electromagnetic field is provided to control a transfer amount of molten metal using a force generated by inducing an electric field and a magnetic field into a nozzle. In a nozzle or flowing down molten metal contained in a tundish into a mold, a nozzle input control system using an electromagnetic field comprises: a nozzle(5) formed in a rectangular column shape; a pair of copper plates(11) that are closely adhered to inner wall surfaces of the nozzle and face each other; a power supply unit(13) that passes through wall surfaces of the nozzle to supply a power source to the copper plates; and a pair of direct current magnets(9) which are spaced in a predetermined distance from outer portions of wall surfaces perpendicular to the copper plate-formed wall surfaces, and which are oppositely directed to each other, wherein a DC current and a DC magnetic field generated when the power source is supplied to the nozzle generate a force for controlling an inflow amount of molten metal flowing into the nozzle.
