Here is one for planar arrays: https://www.researchgate.net/publication/228401193_Electrodynamic_passive_magnetic_bearing_with_planar_halbach_arrays https://www.researchgate.net/publication/228401193_Electrody... Here is one that apparently doesn't need the coils either (haven't checked it beyond the abstract): https://www.sciencedirect.com/science/article/abs/pii/S0304885311001181 https://www.sciencedirect.com/science/article/abs/pii/S03048...

- jacquesm 3y agoNo, I'm referring to a circular arrangement, not a planar one, but the effects are much the same, think of it as a rolled up version of a Halbach array with coils connected across the opposing sides in such a way that bringing the coil closer to the side will increase the attractive force on the other side. It's a pretty clever arrangement, that requires no control electronics and has very low loss once it has centered itself.
