摘要：
已绘制超导环对永磁体施加的力和力矩图。结果表明存在稳定轨道。此外，只要磁体保持在任一轨道内，超导体中的第一临界场就永远不会被超过，超导体保持迈斯纳态。由此产生的无磁滞现象使这类装置成为无摩擦轴承或陀螺仪的理想候选。
英文摘要：
Forces and torques exerted by a superconducting torus on a permanent magnet have been mapped. It is demonstrated that stable orbits exist. Moreover, provided that the magnet remains in any of these orbits, the first critical field in the superconductor is never overpassed and the superconductor remains in the Meissner state. The consequent absence of hysteresis makes these kinds of device perfect candidates for non-frictional bearings or gyroscopes.
