Abstract: In this paper, a new method is proposed for protecting spacecraft against high-energy particle irradiation by using a magnetic shielding system. The principle of the magnetic shielding system and the feasibility in its engineering applications are discussed. A design of such a system is shown with relevant calculations. The results indicate that the design is effective in protecting spacecraft against space electrons up to 0.15 MeV.
