If you have four magnets all stuck together, the magnetic field is the same as if you have one large magnet.


Not if 2 magnets are flipped. Over just one magnet, the pyrolytic carbon (or LK-99) would slide off to the side. Over 4 magnets arranged correctly, it stays in the middle. This is described here: https://www.imagesco.com/magnetism/graphite-levitation-kit.h...

Some superconductors will float and stay over just one magnet, but it's a different story: https://en.wikipedia.org/wiki/Flux_pinning - LK-99 is not of this type as far as I know.
