This looks a lot less like diamagnetism than the previous videos, but is still using way larger magnets than they should need; still very sceptical.
Also a reminder to anybody reading a news article about this: LK99 is likely a ceramic, so the attributes specifically for metallic superconductors would not apply.
Assuming for a moment it is real and works and this class of material is useful for transmitting current with 0 resistance or making magnets, many attributes of other ceramic superconductors also shouldn’t apply given the theory that predicted it says it’s not one of those either.
This also leads to a very very stupid reactionary semantic argument you’ll start seeing more and more over the coming weeks.
I’m honestly more worried about science communicators projecting life-changing properties onto it because “superconductor”, and then the public coming away with “these scientists are all hyperbolic hacks”.
