*基于等离子磁铁的等离子帆推进是一种独特的系统，可以以最小的能量和质量要求利用太阳风的环境能量。与太阳风的耦合是通过产生大范围（~> 30 km）偶极磁场来实现的。与最初的磁帆概念不同，线圈电流在等离子体而不是超导线圈中传导。这样，对于相同的推力，帆的质量减少了几个数量级。等离子体磁体由一对多相线圈组成，它们产生旋转磁场（RMF），驱动等离子体中必要的电流以膨胀并维持大规模磁结构。等离子体磁体通过等离子体电流上的洛伦兹自力展开，以盘状向外膨胀，直到太阳风压力停止膨胀。它实际上不需要推进剂，因为拦截的太阳风补充了携带磁体电流所需的少量等离子体。与固体磁铁或帆不同，等离子磁铁随着太阳风压力的下降而膨胀，以提供恒定的推力。
*Plasma sail propulsion based on the plasma magnet is a unique system that taps the ambient energy of the solar wind with minimal energy and mass requirements. The coupling to the solar wind is made through the generation of a large-scale (~> 30 km) dipolar magnetic field. Unlike the original magnetic sail concept, the coil currents are conducted in a plasma rather than a superconducting coil. In this way the mass of the sail is reduced by orders of magnitude for the same thrust power. The plasma magnet consists of a pair of polyphase coils that produce a rotating magnetic field (RMF) that drives the necessary currents in the plasma to inflate and maintain the large-scale magnetic structure. The plasma magnet is deployed by the Lorentz self-force on the plasma currents, expanding outward in a disk-like shape until the expansion is halted by the solar wind pressure. It is virtually propellantless as the intercepted solar wind replenishes the small amount of plasma required to carry the magnet currents. Unlike a solid magnet or sail, the plasma magnet expands with falling solar wind pressure to provide constant thrust.
