What is Fleming's left-hand rule also called?

Fleming's left-hand rule is also known as the motor rule because it is used to determine the direction of motion in electric motors. The rule provides a simple way to visualize the relationship between the magnetic field, the direction of the current, and the force experienced by a conductor in that field. In this context, the thumb represents the direction of force (motion), the first finger represents the direction of the magnetic field, and the second finger represents the direction of the current. By using this rule, one can easily remember how electric motors convert electrical energy into mechanical energy, illustrating the fundamental principles of electromagnetism in motor operation.

This technical understanding is crucial for operators and engineers in the field, as it aids in troubleshooting and designing efficient motor systems. Other rules, such as the generator rule, relate to different applications and concepts within electromagnetism, which is why they do not align with Fleming's left-hand rule.
