6.13 Fleming’s Left Hand Rule

Use the left hand rule to predict the direction of the resulting force when a wire carries a current perpendicular to a magnetic field

We can predict the direction of the force from the motor effect using Fleming’s left hand rule.
  • Use your First finger (index finger) to point in the direction of the Field
  • Your seCond finger in the direction of the Current (at 90° to the first finger)
  • Your thumb is now pointing in the direction of the force/motion.
  • Remember to always use your LEFT HAND
