Q. What does the middle finger in Fleming’s right hand rule indicate?
Solution:
Fleming’s Right-hand Rule (for generators) shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator’s windings. According to the rule when the thumb, the pointing finger and the middle finger are perpendicular to each other and the thumb has the direction of the applied force and the pointing finger has the direction of the applied magnetic field, then the middle finger will show the direction of the current induced in the conductor. So all the given options are wrong. The diagram shows the idea clearly.
