The inductance calculated in this tool is the self-inductance, which is used in some simulations and is only part of a total loop inductance. In this tool, the variables required are length and wire diameter. Notice that there is not a return path referenced in this inductance estimator. When calculating a loop inductance, the self-inductance as well as the mutual inductance to the return path and the return path's self-inductance are accounted for. Please find our wire (cable) self inductance calculator below.

Wire Self Inductance:
Introduction
The inductance of a single conductor is called self inductance. Self inductance is not typically measured,
since it is only part of a complete circuit loop.
Wire Self Inductance Model
The self inductance of a single wire in free space is defined below.
For this calculation the diameter and length units are in cm.
