1. Movement range for a mobile object (11), whose position is to be detected with respect to a surface (19) in the movement range, wherein themovement range has a ground (21) and the surface intersects the ground along an intersecting line (20), comprising the following features:

  • a first elongate magnetic field generating object (14), arranged at a first distance (d1) from the intersecting line on a first side of the intersecting line in or on the ground;

    a second elongate magnetic field generating object (15) arranged at a second distance (d2) from the intersecting line (20) in or on the ground (21);

    wherein the first magnetic field generating object and the second magnetic field generating object are adapted to generate a magnetic field decreasing with a radially increasing distance with respect to the magnetic field generating object; and

    a generator (16) for controlling the first magnetic field generating object and the second magnetic field generating object with a current and a multiplex mode.
