Electromagnetics: Reducing inductance of a wire loop

Click For Summary
SUMMARY

This discussion focuses on strategies to minimize the inductance of a flexible wire loop. Key suggestions include surrounding the wire loop with a superconducting loop in the same plane and adding a second wire adjacent to the loop, wound oppositely to reduce inductance. The effectiveness of these methods may vary based on the application, particularly at microwave frequencies or for improving the risetime of current switching. Twisting the wires together is recommended to minimize flux leakage.

Given a flexible wire loop of a certain perimeter and planar shape, what are some good ideas to minimise the loop's inductance?
For example, would it work if i surrounded the wire loop with a superconducting loop in the same plane?

I'm not au fait with superconductor properties.

But, in principle, if you added in series a loop adjacent to, but wound oppositely to yours, I think inductance would be minimized. In practice, I'm not sure how this would work out. Are you wanting to use the loop at microwave frequencies, or wanting to sharpen the risetime of current switched through your loop?

I think you could run a second wire next to the loop but short circuited. The effect depends on having small flux leakage, so maybe the two wires could be twisted together.
