Q: What is the primary principle behind the operation of an electric motor?

The interaction between a magnetic field and an electric current. — Electric motors use magnetic fields generated by current-carrying conductors to produce torque.

Q: What component is responsible for creating the rotating magnetic field in a typical AC induction motor?

The stator windings. — The stator windings, supplied with AC power, produce a rotating magnetic field.

Q: What is the function of the commutator in a DC motor?

To reverse the current in the armature windings at regular intervals. — The commutator reverses current to maintain continuous rotational force.

Q: Which of the following components directly experiences the torque in an electric motor?

The shaft. — The shaft is coupled to the rotor and transmits the mechanical torque.

Q: What type of energy conversion occurs within an electric motor?

Electrical energy to mechanical energy. — Motors convert electrical energy provided to rotational mechanical energy output.
