【Abstract】 According to the model of permanent magnet magnetic dipole, we have concluded the axial magnetic field distribution of square magnet and discussed the demagnetizing factor inside the magnet. We measure the surface field of a kind of square hard ferrite which accords with the theoretical value quite well. It proves that the calculation is correct and practical.更多还原
