उत्तर
Fleming's Left-Hand Rule, also known as the Motor Rule, states that the thumb, first finger, and middle finger of the left hand should all be extended such that they are perpendicular to one another. The thumb indicates the direction of the conductor's motion (i.e., the direction of force acting on the conductor) if the first (fore) finger points in the direction of the magnetic field, the middle finger points in the direction of current, and so on.
