Kone,

That is bizarre, very cool data!

Here is interesting experiment in seeing when and how a nortb-only triggering ball effect will turn on and off a SS mosfet relay using 20mm wide neodymium rotor magnets arranged NSNS around in a flat disc rotor.
Look how a North face  behaves normal, but interesting is that a South face also triggers too, but just for only a very short blip right above the leading and trailing edges of th S magnet face.
This of great usefulness to me at least, since if doing sinewave peak coil shorting into caps when taking out power from rotor-magnet inducec generator coils, you will need a very short  blip to the turn-on time of the short circuiting of the generator coil, (to avoid Lenz law while filling cap)
and a rotor of all-S  facing iming magnets (can double as motor magnets) of same size and spacing as the generating rotor magnets, sharing common axle shaft, and  spiining against a N-only hall effevt would work perfect to time the shorting of generator coils into caps so this next experiment
