SUMMARY
The discussion centers on the motor principle and the direction of force on a conductor, specifically addressing the use of the right-hand rule and Fleming's left-hand rule. The right-hand palm rule, which involves positioning the thumb to indicate current and the palm to indicate force, is confirmed as correct for determining the direction of force. In contrast, Fleming's left-hand rule is commonly used in textbooks for motor applications, where the index finger represents force, the middle finger represents the magnetic field, and the thumb represents current. Both rules yield the same results, but the left-hand rule is more prevalent in educational contexts.
