In power transmission why inductance L increases with increased spacing

Click For Summary
Inductance in power transmission systems increases with the spacing between conductors due to the interaction of magnetic flux. As the distance between two wires increases, the area enclosed by the loop increases, allowing more flux lines to fit within that area, which contributes to higher inductance. Although the intensity of the magnetic field decreases with distance, the overall inductance is affected by the total flux linkage across the loop area. The mutual cancellation of flux lines occurs when conductors are close together, but as they separate, the flux lines can add, enhancing the inductance. Understanding these dynamics is crucial for optimizing power transmission efficiency.

so why is L because of the blue flux ignored?
because your blue flux line does not pass through the area enclosed by your current loop.
So it doesn't link the turn(s) of your inductor...

Okay. Thanks a lot.
The reason i didn't draw end view earlier was cause i didnt know what an end view is. Here we have front view, top view and side view.

Ahhh real drafting ! ok, call it front view...
