论文摘要
我们重新审视了在Stokes流中以空间均匀旋转的磁场稳定稳定磁场的永久性磁性刚体的动力学。我们建议根据两个关键的实验参数对完整平衡的分析参数化，并展示其如何带来进一步的理解，从而有助于优化磁化和操作参数。当系统达到最佳的游泳速度时，该系统通常是可动的。提出了一种处理策略，以确保达到正确的平衡。
We revisit the dynamics of a permanent-magnetic rigid body submitted to a spatially-uniform steadily-rotating magnetic field in Stokes flow. We propose an analytical parameterisation of the full set of equilibria depending on two key experimental parameters, and show how it brings further understanding that helps to optimise magnetisation and operating parameters. The system is often bistable when it reaches its optimal swimming velocity. A handling strategy is proposed that guarantees that the correct equilibrium is reached.
