Working of DC motor

Answer»

A motor is anelectrical machinewhich converts electrical energy into mechanical energy. Theprinciple of working of a DC motoris that "whenever a current carrying conductor is placed in a magnetic field, it experiences a mechanical force".The direction of this force is given byFleming's left hand ruleand it's magnitude is given by F = BIL. Where, B = magnetic flux density, I = current and L = length of the conductor within the magnetic field.
