and we still dont know if the field rotate or not.

and we still dont know if the field rotate or not.

It's not important if the field rotates with the magnet or not. The problem results from a uniform field where because it's uniform will simply slide and do no work.
It must be forced to cross a conductor to induce a current and yet because of this it still produces the counter emf.
If it did not then a simple unipolar motor would not operate. A unipolar motor rotated by a mechanical input will become a generator for the same reason.

The principal of counter EMF is what makes all motors and generators work.

The instant any current is produced in a conductor by movement through a magnetic field, that very same current generates an opposite magnetic field that fights the movement direction.

  Look at a speedometer, what more than a rotating magnet?
