We present state-of-the-art high resolution 3D magnetic field mapping on permanent magnets of the (Bx, By, Bz) magnetic field vector components in 3D space, resulting in measurement data with 6 degrees of freedom. These measurements are performed using a high speed 3D magnetic field camera, featuring an integrated 2D Hall sensor array, mounted on a 3-axis mechanical scan stage with a scan range of 300 x 300 x 300mm³ with which measurement speeds of 120mm²/s are obtained with a spatial resolution of 0.1mm x 0.1mm. Volume 3D magnetic field distribution measurements of sensor magnets are performed and analyzed using powerful and versatile data analysis software, which allows virtually unlimited possibilities for the data analysis and quality control of permanent magnets, both in R&D, incoming magnet inspection and production.
