I never met Maxi, but just did a simpel 2D experiment with some of my litte cubic form super magnets, thin iron screwsriver in the middle, 2 magnets same polarity 'in series' at each side at both ends test magnet M1 M2 S M3 M4 [S/N] [n/s] [n/s] O [s/n\][s/n] 'M' are the square magnets, 'S' is the screwriver, bit thinner than the magnets Both ends are N and rejected by a similar magnet N So it depends on the core these magnets: https://panteltje.nl/pub/levitation_cut_img_3051.jpg an even thinner screwdriver and the magnets want to re-ajust position, but if you fix them in position it still works!
