| Abstract: | In this paper,the magnetic scalar potential finite element method for calculating 3 -D permanent magnetic field is described. Through calculating a permanent magnetic field in MRI (Magnetic Resonant Image)system, the author compares the magnetic scalar potential with the magnetic vector potential. The result is that the magnetic scalar potential method needs less time and less computer memory than the magnetic vector potential method. |
