State Fleming's left-hand rule and say what it is used for.
Original Khojo Papers practice question — not from a past board paper.
Answer
Stretch the thumb, forefinger and middle finger of the left hand so that they are mutually perpendicular. If the forefinger points along the magnetic field and the middle finger along the current, the thumb points in the direction of the force on the conductor. It is used to find the direction of the force on a current-carrying conductor in a magnetic field, as in an electric motor.

Explanation
Fleming's right-hand rule is the corresponding rule for induced current in a generator.
