Magnetic field data from magnets or magnetized materials can be collected in 1, 2 or 3 data planes (X, Y & Z) at both the magnet center and magnet edges. The application magnets are positioned in a non-magnetic test stand custom-machined for these measurements. The Hall-effect probes are mounted in a 3D micrometer station or robotic fixture for providing accurate dimensional stepping in 3-planar directions. Hall-effect probes used are periodically calibrated with several traceable reference magnets throughout the measurement and collection.
