摘要
本文对处于交变磁场中的导体环悬浮于空中振动的现象，进行了简单的理论分析，证明了导体环悬浮于空中振动的关键，是由于电感的存在，使导体环受到一个复杂的周期性安培力的作用．
This paper presents a concise and theoretical analysis about the vibration of a conducting ring floating in air which is in an alternating magnetic field and shows that the essence of the vibration of the conducting ring floating in air is the function of inductance which makes the conducting ring being acted upon by a complicated and peoriodical ampere force.
