I was wondering , is it possible to create a loop of any kind of geometry that could rotate in a non homogeneous AC magnetic field and have no net induction within the loop but only have current generated from the effect of Lorentz force on the electrons in the moving conductor ? It is achieved easily in a static magnetic field. In changing magnetic field this in theory can be achieved either by avoiding forming loops around areas of flux or by forming loops with canceling flux between them. I asked this to chatGPT and got an answer that in theory it could be possible but then i tried to draw out loops on paper and soon realized it might not be possible after all.
Another interesting aspect is that when i tried to see the direction of current in the loop as it rotates within a AC magnetic field that is bipolar for example like those found in universal motor stators , it seems to me the direction of the Lorentz force generated current in the loop is the same as that generated by induction, is this always the case in loops rotating in AC fields?
