or the flux must cut the conductor as in AC generators where magnetic poles rotate by stationary coils. the only difference here is that I dont have poles on the rotor instead the whole rotor is a single pole at any given moment in time , but since its flux is AC the poles change repeatedly with a given frequency so then the question is does the flux lines cut the stator coils or do they need a physical rotating pole to do that , this question is still open.
The flux cutting the conductor is not a different situation, it is the same one from another point of view.
You have asked an either/or question in which both answers could be wrong. If when powered with DC your system does not induce any EMF at any point in the cycle, then it will do no work powered with DC or AC.

Ok I think I got it , for this to work it would need to have poles on the rotor , or atleast a single pole but with differences in the flux at some places , which would correspond to not a solid rotor geometry.
Well I have another question then, before I mess up another thread maybe I can just ask it here.
Could a faraday disc (homopolar) generator work with a rotary transformer used as the current path from the rotor to stator instead of brushes, or slip rings, if we use a changing magnetic field as the discs field source ofcourse?

I don't know if it will help here, but have you looked at Tesla's rotating magnetic field. There was a spinning egg application here...forgot the title.

do magnetic flux lines rotate or no
