Question
State the rule to determine the direction of force experienced by a current-carrying conductor in a magnetic field.
Answer
Fleming’s left hand is used to determine the direction of force experienced by a current-carrying conductor in a magnetic field.
The rule states that if the thumb, the first finger and the middle finger of the left hand be held mutually perpendicular to each other in such a way that the first finger points to the direction of the magnetic field and the second finger to that of the current then the numb will indicate the direction of motion of the conductor.
