In any rotating machine that part which houses the conductors and in which e.m.f. induced is to be utilized is called

The correct answer is: A. Rotor

The rotor is the rotating part of an electric motor or generator. It is usually made of a magnetic material, such as iron or steel, and is surrounded by a stator. The stator is the stationary part of the motor or generator, and it contains the windings that produce the magnetic field. The rotor is turned by the magnetic field produced by the stator, and this motion is used to power a machine or generate electricity.

The other options are incorrect for the following reasons:

• Option B: The stator is the stationary part of the motor or generator, and it contains the windings that produce the magnetic field. The rotor is turned by the magnetic field produced by the stator, and this motion is used to power a machine or generate electricity.
• Option C: The field is the magnetic field produced by the stator. The rotor is turned by the magnetic field produced by the stator, and this motion is used to power a machine or generate electricity.
• Option D: The armature is the part of the motor or generator that houses the conductors and in which e.m.f. induced is to be utilized. The rotor is the rotating part of the motor or generator, and it is usually made of a magnetic material, such as iron or steel, and is surrounded by a stator. The stator is the stationary part of the motor or generator, and it contains the windings that produce the magnetic field. The rotor is turned by the magnetic field produced by the stator, and this motion is used to power a machine or generate electricity.
