摘　　要：利用PASCO实验平台的磁感应强度测量传感器，测量了方形永磁体轴线处不同高度上的磁感应强度．然后根据磁悬浮陀螺稳定悬浮的条件和方形永磁体磁场分布的解析表达式，提出了确定陀螺稳定悬浮高度范围的一种简化方法．实验测量表明，所采用的简化方法能方便确定陀螺悬浮的高度范围．By using the PASCO Magnetic Field Sensor, the magnetic inductions of a set of points above the center of the square magnet are measured. Then, based on the conditions of the Levitron’s stability and the analytical expression of the magnetic field of the square magnet, a simplified method is presented to predict the height range of Levitron’s stability. The height range of Levitron’s stability is also measured during the period of its suspension. By comparing these results, it is found that the simplified method can predict the height range of Levitron’s stability over a square magnet conveniently.
