小型永磁体和大块高 Tc 超导陶瓷材料之间的磁化力已被测量，并显示出作为磁体和超导体之间距离的函数的明显磁滞行为。已经产生了高达 2500 达因的磁力，无论是垂直于超导体表面还是切向于超导体表面。然而，磁体的小运动可以获得接近可逆的力，这被认为与磁通钉扎有关。
Magnetization forces between small permanent magnets and bulk high Tc superconducting ceramic materials have been measured and show marked hysteretic behavior as a function of the distance between the magnet and superconductor. Magnetic forces of up to 2500 dyn, both normal and tangential to the superconductor surface, have been made. Near‐reversible forces are obtained for small motions of the magnet, however, which are believed to be related to flux pinning.
