Self-Inductance with Neumann Formula

Calculate the self-inductance of wire loops of arbitrary geometry

While closed-form expressions for inductance can be found for many common shapes of wire coils, this tool allows you to predict the inductance of wire coils of arbitrary shape.
This tool was used in the development of "Smart Braid" sensors.
This is a numerical implementation of the technique described by Richard Dengler in
"Self inductance of a wire loop as a curve integral"
(http://arxiv.org/abs/1204.1486)
Note that the calculations accomplished with this script can be calculated much more quickly with the freely available software FastHenry2 (http://www.fastfieldsolvers.com/products.htm#fasthenry2). A script that generates Smart Braid Geometry for FastHenry2 is available at:
