Abstract
A device and a method for stabilising a metallic object of magnetic material. The metallic object is transported along a transportation path or plane. The plane includes a transportation direction and is parallel to the longitudinal direction of the object therein. A sensor is arranged to sense the valve of a parameter depending on the position of the object with respect to the plane. An electromagnetic actuator is arranged to apply a magnetic force to the object in respone to the sensed position. The magnetic force has a force component directed transversely to the transportation direction and transversely to the plane.
