The magnetic sail is a high-specific-impulse propellantless propulsion system that utilizes the interaction between solar wind particles and the artificial dipole magnetic field generated by a large spacecraft coil to produce thrust. It has great potential in deep space exploration. However, practical application is limited due to the requirements for large coil size and high working current. To address this, a design for a rotating magnetic sail driven by a high-speed motor and revolving around the dipole axis of the coil is proposed. Using the three-dimensional particle tracing method, the dynamics of ions and electrons are considered in the analysis. The rotating magnetic sail generates an induced electric field that enhances the exchange of momentum between the surrounding plasma and the spacecraft. The results indicate that the rotating magnetic sail enhances the induced current responsible for plasma charge separation and the generation of polarized electric fields. The thrust of the magnetic sail increases significantly with rotational speed and is influenced by the plasma velocity. The study reveals that in the solar wind, the size of a rotational magnetic sail can be reduced to approximately 20% of the minimum size of a static magnetic sail, while in low Earth orbit (LEO), the size can be reduced to around 1%, while maintaining the same level of thrust.
