Claim One:
1. An arrangement for characterizing magnetic systems based on an initialized set of input parameters of the magnetic system, the arrangement comprising: a magnetic field sensor for measuring the magnetic field distribution of the magnetic system of a magnet, means for determining an optimal expected magnetic field distribution of the magnetic system by optimizing one or more parameter(s) selected from the set of input parameters of the magnetic system, wherein said means for determining said optimal expected magnetic field distribution comprises i) means for determining an expected magnetic field distribution using a theoretical simulation model and based on said set of input parameters, said expected magnetic field distribution comprising precalculated simulation data, ii) means for comparing said expected magnetic field distribution to said measured magnetic field distribution value, and iii) means for using an optimization scheme to obtain an optimized expected magnetic field distribution of the magnetic system, means for comparing said optimal expected magnetic field distribution of the magnetic system to the measured magnetic field distribution of the magnetic system by forming a residual image, and means for performing statistical image analysis on the residual image to yield quantitative parameters reflecting imperfections and/or quality of the magnetic system and to determine whether the magnetic system passes or fails a quality control.
