Abstract :
In this paper, the solution based on the coupled problem the angular distances between the slots of the magnetizing fixture were determined. A prototype fixture was built and tested. The output from the Hall sensor placed at 1 mm from the disc magnet. The magnetic fields was sensed with the resolution of 1000 points per one degree, Based on the magnetization was detected as +/- 0.5 degree per pole.
