摘要

理论和实验表明，磁力搅拌器能提供一种简单的被动磁悬浮方法，在这种方法中，悬浮子可以长时间地稳定悬浮。研究了这一现象，理论分析了悬浮的起因，并定量分析了悬浮子的运动(垂直振荡、旋转和摇摆的组合)，实验结论与力学模型分析结果非常吻合(运用龙格库塔方法解二元二阶微分方程组)。本研究对双向微流控泵的发展具有启示意义，提供了复杂的商业悬浮器的替代方案。

Abstract:

Theoretical and experimental results show that magnetic agitators can provide a simple passivemagnetic levitation method in which the levitator can be suspended stably for a long time． It studied this phenomenon，analyzed the causes of the suspension，and quantitatively analyzed the motion of the levitator (a combination of vertical oscillation，rotation and swing)．The experimental results agree well with the mechanical analysis model (using the Ｒunge-Kutta method to solve the binary second-order differential equations)．This research has implications for the movement of artificial swimmers and for the development of bidirectional microfluidic pumps，providing an alternative to complex commercial suspensors．
