A method for determining a position of a movable object is disclosed. The method comprises generating an electromagnetic exciter field. The electromagnetic exciter field is configured to excite the movable object to develop a magnetic response field. Further, the method includes determining a plurality of measurement values for the magnetic response field by measuring the magnetic response field at a plurality of predetermined measuring positions. Further, the method includes determining the position of the movable object based on a comparison of the plurality of measurement values with reference measurement values. Here, one position of the movable object is allocated to each of the reference measurement values. Further, the reference measurement values are each determined by a simulation.
