摘要: 利用牛顿力学中的稳定性理论对磁悬浮陀螺稳定悬浮的条件进行了分析,在实验上对磁悬浮陀螺底座磁场的空间分布进行了测量,将理论分析和测量的数据结合起来从理论上预测陀螺稳定悬浮的区域范围,再将实验上实际观察到的稳定悬浮区域与之对比,得到了一致性的结论,由此得出了磁悬浮陀螺稳定悬浮的条件.

Abstract: With the help of the stable theory in Newtonian mechanics,the appropriate stable suspension condition of levitron is researched.The space distribution of magnetic field stimulated is measured experimentally by the base of the levitron.The combination between the theoretical analysis and the experimental measurement predict the district of the stable suspension of levitron,which is in agreement with the experimental observation.Then the stable suspension condition is grasped.

Key words: levitron, stability, potential well, distribution of magnetic field
