Well, from what we see on the pic, I guess the magnets are piled up on a wood stick this way :
And so, the magnets push each other

Edit : But these must be some real tough magnets

Are you asking how those permanent magnets stay floating? Because I don't believe you can create a hollow ring permanent magnet with that polarization. Instead, opposite ends of the ring would be the poles. Solid circles can be, but then you couldn't put them around a stick.

>/sci/ doesn't know basic EM

It doesn't, at least not with permanent magnets, go read about Ernshaw's theorem.

If you really want to know go though the EM modules on OCW and start studying calculus. The math is horrendous on em stuff. That's why it's left out of the introductory physics texts.

i saw a vidya of some dudes making 3d printed magnets the other day, with quite complex polar patterns

but that can't be how this thing works

How retarded are you? You can buy these in a toy store.
