9 Magnetic Levitation

指导老师：陈元杰

Under certain circumstances, the “flea” of a magnetic stirrer can rise up and levitate stably in a viscous fluid during stirring. Investigate the origins of the dynamic stabilization of the “flea” and how it depends on the relevant parameters.

1. a viscous fluid 可以选择哪些？
2. a magnetic stirrer 的尺寸（也可能是相对于容器的相对尺寸）、形状对结果会有多大的影响？
3. stirring 怎么定量测量？
