The rotor of fan is shown as a series of circles arranged in a circular manner. From youtube videos, I came to know that this is sort of a top view and the circles actually represent conductors through which current 'can' flow into the screen or come out of the screen (towards the viewers). I wonder as to what happens to the current that arises in these conductors (due to the induction of EMF).
Where do the electrons flow to ? There has got to be some path, which makes that path a conductor, and hence susceptible to be affected by lorentz force.
So why isn't that shown ? (Diagrams would be highly helpful)
