The flux set up by the armature current, which does not cross the air gap and takes a different path, is called:
Show Hint
Leakage flux is undesirable because it does not contribute to the machine's intended function and increases energy losses.

- Leakage flux
- Main flux
- Cross-magnetizing flux
- Demagnetizing flux

The Correct Option is A
Solution and Explanation
Leakage flux refers to the magnetic flux produced by the armature current that does not cross the air gap and follows a different path. It does not contribute to the useful flux that interacts with the field in the air gap. This type of flux can lead to additional losses and lower the machine's efficiency.
On the other hand, the main flux is the useful flux that crosses the air gap, interacting with the rotor or stator to generate torque or electrical power.
