    摘要： A metal strip stabilization apparatus according to one aspect of the present invention includes a displacement measurement unit, a control unit, and an electromagnet unit. The displacement measurement unit measures a displacement of a metal strip during traveling in a non-contact manner. The control unit generates a vibration suppression signal for controlling vibration suppression of the metal strip and a position correction signal for controlling position correction of the metal strip based on a measurement signal of a displacement of the metal strip provided by the displacement measurement unit. The electromagnet unit includes a vibration suppression coil for generating a first magnetic force based on the vibration suppression signal, a position correction coil for generating a second magnetic force based on the position correction signal, and a core about which the vibration suppression coil and the position correction coil are concentrically wound, and which leads the first magnetic force and the second magnetic force to the metal strip. The number of turns of the position correction coil is two times or more to five times or less of the number of turns of the vibration suppression coil. The electromagnet unit suppresses vibration of the metal strip by the first magnetic force, and corrects a position of the metal strip by the second magnetic force.
