You musnt forget the fields outside the ring.they do play a roll too

Yup. Not only that. Even if the upper side attract and lower side repels (they do), the same forces at the very closest also want to countertorque.


I made this hand held stator. I felt that the rotor didn't have torque around the hub, but the hub felt to be bore like the circumference of a "virtual" hub closer to the most narrow gap between rotor and stator - somewhere between the physical hub and the narrow gap.


Anyway, the rotor did not spin. I expected that, but built it to learn why not.
