Description by the author, translated by Google Translate: I need to clarify and explain: the sample is standing above the magnet, and it will immediately return to standing when pressed with tweezers in front of the video, similar to the anti-magnetism of Koreans. In the back of the video, because the sample is too small, I dare not push it with tweezers, and it is easy to break the sample, so I moved the paper a little sideways, and it can be seen that the sample is still diamagnetic, and it is not that the moving magnet is moving with the magnet. Whether it is related to flux pinning or superconductivity remains to be further verified. Please treat it rationally! Original: 我需要澄清和解释一下：样品在磁铁上方是站立着，视频前面用镊子去压它马上又恢复站立状态，类似韩国人的抗磁性。视频后面因为样品太小，没敢用镊子去推，容易把样品搞碎，所以稍微横移了一下纸张，可以看到样品还是呈抗磁性，并不是移动磁铁跟着磁铁在移动。是否属于磁通钉扎或者超导相关还有待进一步的验证。请理性看待！
