| 摘 要： | 由于磁通量的变化，交变磁场中的导体中会感生涡流，产生涡流反过来会产生磁场，与交变磁场形成斥力作用，利用此斥力作用可以实现导体的悬浮。利用此原理制作了磁悬浮实验，涡流的存在得到了验证。结果表明，交变磁场变化越大，悬浮对象材质越轻，截面积越大，悬浮效：果越好。此外，利用涡流的不均匀分布制作了驱动装置。

| Abstract: | Because of the variation of magnetic flux, the eddy current will be induced in the conductors when they are placed in the alternating magnetic field, And the eddy current, in turn, will generate a magnetic field which is repulsive with the alternating magnetic field. The suspension of the conductor can be achieved by the repulsion. Based on this principle, a magnetic suspension experiment was designed and the presence of the eddy current was verified in this paper. The results showed that the larger the change of the alternating magnetic field was, the lighter the suspension objects were, the greater the cross - sectional area was, the better would the suspension be. In addition, a driving device was produced by the non - uniform distribution of the eddy current. |
