I connected everything together, put magnets in the 8 pockets of the rotor and holding the hall sensor in my hand I moved it around to see if my circuit was switching the toroids on and off as expected. It didn’t, the hall sensor did not sense the magnetic field at the poles at all. I tried above and below. As I moved it between those two  positions it turned on near the center of the magnet, but at this position it didn’t turn off when I turned the rotor. Anyway, I had some changes to make and removed all the magnets from the pockets. When I was ready to try again the hall sensor behaved as expected and I didn’t think more about it. At least not before it happened again. Thinking I had blown the sensor I checked with an extra magnet. No problem at all. This lead me to believe the magnetic field around the rotor had two different and stable configurations. One that behaves as I expect and another one. I experimented for a while and so far it seems that when I put the magnets in the pockets I get one or the other configuration, but I never know which one.
