A magnet bar has been installed in the vertical rotation axis of a coil. Which of these drawings represents an AC generator?
2. Relevant rules
Fleming's right-hand rule.
The Attempt at a Solution
Fleming's right-hand rule assumes that the coil is in motion, but in the drawings the magnet is in motion, and that's what made me not able to know how to apply it correctly here. So could anyone give me some hints, please?
I think both (a) and (b) could be AC generators, but the problem statement says that only one is correct.
