Abstract :
Factors contributing to distortion of the field generated by permanent magnets, such as fabrication and material tolerances, are analyzed using the harmonic series expansion of the magnetostatic potential. The power spectrum is influenced by the number of discrete blocks and the number of layers of the magnetic structure. Ferromagnetic plates, acting as spatial filters inserted in the magnetic structure, reduce the distortions due to magnetization tolerances by approximately 60%
