उत्तर
Stretch the forefinger, middle finger, and the thumb of your left hand mutually perpendicular to each other. If the forefinger indicates the direction of the magnetic field and the middle finger indicates the direction of the current, then the thumb will indicate the direction of motion of the conductor.
