More and more applications enlist magnets and the according magnet sensors for position, fixation or tracking purposes. For optimal system functionality, both parts have to meet very specific standards. While the magnet sensors may be calibrated all in the same manner, the characterization of the respective magnets is more complex. Depending on the application, we will find mostly dipole permanent magnets, but the geometries ranging from small tablets to vast cuboids or big, thin rings of various materials. In order to characterize these magnets, there is a range of measurement systems from very small sizes to medium-sized magnets based on the far-field theorem for dipole magnetic fields. The larger the geometry on permanent magnets becomes the harder these measurements can be enabled, as the magnetic response becomes increasingly smaller. The recent technology development allows the characterization of magnets up to 50 Am² based on a completely new sensor set-up using multiple orders of the magnetic field for the determination of the magnetic moment of big magnets. Equipped with Hall sensors surrounding the measurement area, it guarantees the same accuracy as the m-axis systems for smaller magnets with a system the same overall size.
