In this paper, the three-dimensional magnetic field created by non-periodic magnet arrays is calculated analytically. The analytical expression of magnetic field is derived by using magnetic charge model. The influence of ferromagnetic boundaries is formulated with image method. Finally, we compare the results determined by analytical calculation to those from finite element simulation.
