Which law is used to find direction of rotation of motor?

The direction of the rotation of the motor is determined by the Flemings left-hand rule. Flemings laws can be summarized as whenever, a current-carrying conductor comes under a magnetic field, there will be a force acting on the conductor, and on the other hand, if a conductor is forcefully brought under a magnetic field, there will be an induced current in that conductor.

How to Calculate EMF of DC Motor using EMF Equation?
