目前，感应排斥型超导磁悬浮系统正在许多国家进行深入研究。该系统中的升力是由飞行器上的超导磁体和导电板（主要是铝板）或短路的接地线圈产生的。使用导电板的系统称为片状轨道系统，使用短路线圈的系统称为环形轨道系统。结果表明，磁阻尼和刚度系数不仅与车辆垂直运动直接在薄板中感应的涡流密切相关，而且还与车辆垂直运动导致车辆线圈电流变化而感应的另一种涡流密切相关。使用数学模型进行空间谐波分析，以阐明车辆线圈的端部效应，并对结果进行讨论。
The induction repulsive-type superconducting Maglev system is now under intensive study in many countries. The lift force in this system is produced by the superconducting magnet on the vehicle and the conducting plate (mainly aluminum plate) or the short-circuited ground coil. The system using the conducting plate is called the sheet track system and the system using the short-circuited coil is called the looped track system. It is shown that the magnetic damping and stiffness coefficients are closely associated not only with the eddy current induced in the sheet directly by the vertical motion of vehicles, but also with another kind of eddy current which is induced by the variation of vehicle coil current due to the vertical motion of vehicles. A mathematical model is used to perform a space harmonic analysis to clarify the end effect of vehicle coils, and the results are discussed.
