Over a handheld neodymium magnet.
None of the videos have yet shown complete 'levitation', they all have a corner on the surface. But still, not behavior that anyone has ever seen from lead before.
- rvnx 3y agoBut couldn't it just be a magnet ? I don't understand how it's a proof. You can already do what is in the video (and even better), with for example, pyrolitic carbon ? https://en.wikipedia.org/wiki/Pyrolytic_carbon https://en.wikipedia.org/wiki/Pyrolytic_carbon
- aeneasmackenzie 3y agoIt’s not proof, but if it wasn’t even diamagnetic it would be over. It couldn't just be a magnet, it is repelled from both ends of a normal magnet, according to Chinese lab videos you can find in the thread.
- marshray 3y agoLead weighs a lot more than pyrolytic carbon.
- zarzavat 3y agoHave you seen videos of pyrolytic carbon? A thin sliver of it barely hovers on top of a huge magnet. It doesn’t stand erect. Same effect as LK99 but much smaller magnitude.
