@e2matrix Thanks for the interesting feedback on your experiments. I think that the friction coefficient of the spheres against the glass walls have a very important effect on the behavior of the spheres. It is possible that the humidity of the air, or perhaps a question of temperature, generally very different between outside and inside, have an influence on this coefficient, which would explain the differences, as well as the time to recover the old behavior when we go from one environment to the other. It is also possible that the rolling of the spheres changes very slightly the surface state of the glass, leading to differences from one experiment to the other. Only hypotheses... ...
I definitely find this phenomenon interesting that the magnets seem to know which way is up against gravity.
...
Magnets are subject to gravity, so they necessarily "feel" it. The surprise is to see the same effect against gravity whatever the direction of rotation of the cylinders. This is why they talk about time symmetry breaking.
