Abstract: Embodiments described herein relate to devices and methods for determining a magnetic field distribution of a magnet along a main surface of said magnet. An example device for determining a magnetic field distribution of a magnet along a main surface of said magnet includes an arrangement of at least two independent magnetic field camera modules being arranged in a fixed relative position with respect to each other, each magnetic field camera module being adapted for measuring a magnetic field distribution to which it is exposed by means of a respective detection surface. The device also includes a means for providing a predetermined relative movement between the main surface and the arrangement to thereby scan the magnetic field distribution of the magnet along the main surface.

Abstract: The present invention relates to a new method for characterizing magnets, magnetic assemblies (combinations of magnets) and magnetic materials. In what follows, these will be called under the common term ‘magnetic systems’. The method is based on obtaining quantitative properties of the magnetic system by combining magnetic field measurement data and theoretical modeling or simulation data. The input parameters of the theoretical model are optimized using an optimization method in order to obtain a best fit to the measured data. In this method, the present invention involves precalculating magnetic field distributions prior to the optimization execution in order to considerably speed up the process. Combining this advanced data processing with fast magnetic field mapping using e.g. a magnetic field camera, allows real-time measurement and data analysis of magnetic systems for applications in e.g. quality control of such magnetic systems.
