| 摘要 |
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. |
