Q. State Fleming's left hand rule.
Fleming's Left Hand Rule.
The forefinger the middle finger as well as the thumb of the left hand are stretched in mutually perpendicular directions. If the forefinger points in the path of the magnetic field the middle finger points in the direction of the current then the thumb points in the direction of the force on the conductor.
