When we detect space particles, electrons from space will damage the detector and reduce its life. The electrons can also be the back ground and reduce sensitivity for detecting of nuclei. To solve this problem, we use the sweeping magnet to deflect the electrons. Through the finite-element analysis, we can design the sweeping magnet and realize the ability of deflecting electrons. To avoid the leakage of the magnetic field, the shielding of the magnet has to be considered. In the article, we compare the simulation results with the experiment test data. Finally, some suggestions have been made for the design of the magnet.
