该文叙述了一种自行设计制作的既简单方便又经济实用的测试超导体与永久磁体间相互作用力的实验装置，该装置主要由三部分组成：（１）样品与永久磁体间距离的测量，精度达０．００５ｍｍ，（２）用永久磁体和电子称实现的悬浮力测量，（３）样品盒和液氮输送。借助该装置，对同一样品在不同高度场冷（ＦＣ）情况下进行测试，研究了捕获磁通的大小对相互作用力的影响；通过用不同永久磁体对同一样品的Ｆ－Ｚ曲线的测试，研究磁场分布对相互作用力的影响，通过测试同一永久磁体与不同工艺样品的Ｆ－Ｚ曲线，并进行比较，可以判断样品制备工艺之优劣。通过对同一样品在相同条件下的多次反复测量，其Ｆ－Ｚ曲线重复性很好，证明用该装置测得的数据是可靠的，有很好的参考价值，它能定量的反应出样品与永久磁体间的相互作用力和两者间距离的关系，不仅为我们分析样品的制备工艺提供了科学的分析手段，而且节约了大量科研经费．
This paper describes a self-designed and experimental apparatus which is simple, convenient and economical to test the interaction force between superconductor and permanent magnet. The device consists of three parts: (1) Measurement of distance between sample and permanent magnet, Accuracy of 0.005mm, (2) Suspension force measurement with permanent magnet and electronic scale, and (3) Cartridge and liquid nitrogen delivery. With the aid of this device, the same sample was tested under different height field conditions (FC) to study the effect of the magnitude of the captured flux on the interaction force. By testing the F-Z curve of the same sample with different permanent magnets, The effect of magnetic field distribution on the interaction force is studied. The F-Z curves of the same permanent magnet and different process samples are tested and compared to determine the advantages and disadvantages of the sample preparation process. The repeated measurement of the same sample under the same conditions, the F-Z curve repeatability is very good, that the data measured by the device is reliable, a good reference value, which can quantitatively reflect the sample And the interaction between the permanent magnet force and the distance between the two, not only for our analysis of the sample preparation process provides a scientific analysis, but also saves a lot of research funding.
