Electromagnetics: Reducing inductance of a wire loop

  1. Jun 6, 2015 #1
    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.
