What does the term "induction" refer to in Induction Motors?

The term "induction" in the context of induction motors specifically refers to the process by which a magnetic field induces an electric current in the rotor. In these motors, an alternating current flowing through the stator windings creates a rotating magnetic field. This dynamic field then cuts through the rotor conductors, inducing a current due to electromagnetic induction—this is a fundamental principle of electromagnetism described by Faraday's law.

As the rotor current interacts with the magnetic field, it generates torque, causing the rotor to turn and thus producing mechanical output. This induction is essential for the operation of the motor because it allows it to function without direct electrical connections to the rotor. The effectiveness of this induction determines the efficiency and power output of the motor.

The other options relate to various aspects of motor technology but do not accurately define the term "induction" within the specific framework of induction motors.
