What will happen if you put a magnet inside a centrifuge machine?

Question

will the magnet get all messed up?

Answer 1

Not at all.

Spinning a magnet has no effect, gravity has no effect* and passing a permanent magnet through a weak field like the Earth's magnetic field has no effect.

*until you get to an acceleration that causes the magnet to break. Rare-earth magnets are very fragile
