This figure seems to be turning centering around the center of bar magnet. Both bar magnet even,
this are synchronizing (same frequency with namely) it should be gravity, if it is turning.
In this case, it is also possible that the frequency of the bar magnet of the other, is the multiple of the other.
Also this, should become repulsive force, if it is synchronizing as a/the N pole and N pole, S pole and S pole it each other.
Yet, this is unstable and the abnormal pole fellow comes to each other right away. If my reasoning is correct this is the
reason that there is not repulsive force in gravity.
