根据永磁体的等效线圈电流模型，利用旋转磁头的角矩方程，通过简单的分析，估算出磁头的磁悬浮原理。三维静态分析给出了磁顶可以保持悬浮的区域的形状和大小。基于磁顶的角矩方程，采用龙格-库塔法对悬浮磁顶进行了三维动力学分析。静态和动态分析都很好地描述了悬浮磁力陀螺的实验行为。
The principle of magnetic levitation for the magnetic top is estimated by a simple analysis based on the equivalent coil current model for a permanent magnet, with the equations of angular moment of a rotating magnetic top. The three dimensional static analysis gives the shape and size of the area where a magnetic top can be kept levitating. The behavior of a levitating magnetic top is analyzed by the three dimensional dynamic analysis based on the equations of angular moment of a magnetic top using the Runge-Kutta method. Both static and dynamic analysis well described the experimental behavior of a levitating magnetic top.
