1. A device for separating elongate magnetizable objects from a material stream by length, which device comprises:
a magnetic field, which magnetic field is homogeneous in a field zone;
a transport device with a transport surface for carrying the material stream through the field zone in a transport direction, wherein the field direction in the field zone is oriented at right angles to the transport direction; and
a separating device for carrying the elongate magnetizable objects separated by length out of the field zone in a separation direction, which separating device comprises at least one take-up element which travels a path running at least partially through the field zone, wherein in the path in the field zone the minimum distance between the at least one take-up element and the transport surface is a first distance which is smaller than or equal to a greatest main dimension of a cross-section of the field zone parallel to the transport surface.
