- TL;DR Summary
- I am looking for an intuitive explanation to why the inductance of a straight wire is larger for thinner wires.
I know that the whole topic of inductance in a straight wire is complicated (and has led to some heated discussions in this forum ). I followed Rosa's derivation and can see that it leads to an inverse relation of the inductance to the wire radius, and from what could understand, the point is that with thinner wires there is more "space" between the edge of the wire and infinity to integrate across. Is that it, or does someone have a better intuitive explanation for this relationship?
