प्रश्न
Name and state the law which is used to determine the direction of force on a current carrying conductor placed in a magnetic field.
उत्तर
Fleming's left hand rule: Stretch the forefinger, middle finger and the thumb of your left hand mutually perpendicular to each other. If the forefinger indicates the direction of magnetic field and the middle finger indicates the direction of current, then the thumb will indicate the direction of motion of conductor.
