Put this abstract into Google:
"When a current is passed through a ball bearing it can act as a
motor.
This curious effect was pointed out by Milroy. The present paper
gives a
theoretical analysis of this effect. The motor can run in either
direction on both dc and ac. It can be self-starting on dc. Some
experimental results are presented in support of the theory."
The second search result has the link:

The entire paper can be downloaded by clicking the link as it
appears in
the search results.
It contains lots of math.
