Is the current in the correct direction in this image describing a one phase generator?
OP @clone is correct in saying the diagrams do not represent a generator. Curling the fingers of the right hand around the wire, with the thumb pointing in the direction of current flow assuming a generator results in the contradiction of the magnetic field being reinforced on the leading side of the rotor, not the trailing side. The contradiction means the original assumption was incorrect, and that the diagrams show a motor.
