A First-Order Assessment of Permanent Magnet Deflection for Space Radiation Protection

Year: 2026

Type: article

Abstract: We present a preliminary study of the feasibility assessment of a magnetic shield designed to protect a space probe from cosmic radiation via magnetic deflection using neodymium permanent magnets. This work is based on theoretical considerations whose preliminary indications are intended to provide the base for future Monte Carlo simulations and laboratory validation. The novelty of our approach is the use of a magnetic shield whose competitiveness with conventional passive absorbing shielding is not investigated here but deserves to be the topic of upcoming work. The primary objective is to protect a spacecraft from the flux of charged particles emitted by the Sun. To achieve this, we will combine theoretical modeling and numerical simulations, followed by the construction of a prototype to be tested in a laboratory environment and and a potential future CubeSat-scale experimental validation.
