Playing around with my magnets I noticed something odd to me with a microwave oven toroid magnet and a small button neo. I attached the small neo so it could roll around the perimeter of the toroid. I noticed it would settle in basically 3 spots or points. These points seemed to have the strongest attraction. The points were divided evenly seemingly making an equilateral triangle. Is there a known reason for this?

This publication describes the "Edge Currents" of PM's in Section 8. The "Edge Currents" are the major effect when considering how magnets attract and repel from each other.
