A coupling magnetic field inside a rotating machine or static machine ...
Explanation:

Mechanical parts:
- In a rotating machine or static machine like transformers, the coupling magnetic field is primarily associated with mechanical parts.
- Mechanical parts such as rotor, stator, core, and shaft play a crucial role in creating and interacting with the magnetic field.

Electrical parts:
- While electrical components like windings and conductors are essential for the functioning of the machine, they are not directly involved in the coupling magnetic field generation or interaction.
- The electrical parts serve to carry the induced currents and interact with the magnetic field created by the mechanical components.

Both electrical and mechanical:
- The coupling magnetic field is a result of the interaction between the magnetic field produced by the mechanical parts and the electrical currents induced in the electrical components.
- Therefore, it involves both electrical and mechanical elements working in conjunction to ensure the proper operation of the machine.

Either of the electrical or mechanical parts:
- While both electrical and mechanical parts are crucial for the overall operation of the machine, the coupling magnetic field specifically pertains to the interaction between the mechanical components and the resulting magnetic field.
- It is the mechanical parts that primarily influence the generation and behavior of the coupling magnetic field within the machine.
