@mathoph26 all the observed behaviour can be explained by ferromagnetism, no need for diamagnetism. Still very interesting though, copper and lead showing ferromagnetic properties...

@off6848 copper is even irrelevant here, could have been an insulator. Andrew McCalip just found out that Fe impurities seem to cluster, creating iron bits large enough to levitate the whole sample.

How could Sabine fall to this LK-99 flux pinning video? It was almost immediately exposed as a hoax, and now the user who posted it admitted the hoax and retracted the video. Also, it was demonstrated that an insulator with inclusions of ferromagnetic can behave just exactly the same way, so there's no suspected diamagnetism here either. I know, disappointing...

@Zeuskabob1 wrong. See arXiv:2308.03110 - it was demonstrated how an insulator with ferromagnetic inclusions can half-levitate, reproducing all of the behaviors we've seen from LK-99 original and replication efforts so far.
