D. Electrostatic attraction
Answer:B
What is the principle behind the operation of a stepper motor?
A. Electromagnetic induction B. Magnetic reluctance C. Piezoelectric effect D. Electrostatic attraction
Explanation: The operation of a stepper motor is based on the principle of magnetic reluctance. The rotor aligns itself with the changing magnetic fields produced by the stator, resulting in rotational movement.
