Summary:A system for detecting a magnetic flux includes: a magnetic-flux-generating coil having a first and second excitation-track elements extending essentially parallel to a reference plane; a flux-conducting structure for guiding the produced magnetic flux; and a flux-detecting coil having a first detection-track element for measuring at least a portion of the produced magnetic flux, the first detection-track element extending in a first plane defined by the first and second excitation-track elements between the first and the second excitation-track elements. The projection of the excitation-track elements of the flux-generating coil onto a projection plane extending parallel to the reference plane essentially covers the projection of the flux-conducting structure onto the projection plane, at least in the region of the windings of the flux-generating coil.
