摘要
论述一台高临界温度超导体磁悬浮列车物理课堂演示装置，该装置为一个盛放高临界温度超导体的列车模型，在具有磁束缚的封闭磁轨道上方悬浮；或在磁轨道下方倒挂＂悬浮＂．并可在直线电机加速装置或旋转磁场加速装置作用下，沿这一长度约为１．７ｍ的封闭磁轨道，以悬浮或倒挂＂悬浮＂状态无摩擦地连续运转．
A closed magnetic orbit is constructed with magnetic confinement and a small car is comprised of high-temperture superconductor.When this superconductor is cooled by liquid nitrogen down to 77K it become superconductive and the small car moves continually and frictionlessly along the magnetic orbit of abut17m long by applying linear motor or rotating field.The small car can aslo move and hang in space below the magnetic orbit.
