A. To generate electromagnetic fields B. To increase the motor’s speed range C. To provide mechanical stability D. To interact with the stator’s magnetic field
Explanation: The rotor’s teeth or poles in a stepper motor are designed to interact with the stator’s magnetic field. The magnetic attraction and repulsion between the rotor and stator allow for controlled and precise movement of the motor.
