Description
The inductance calculated using this tool is the inductance of the loop bounded by the two coplanar flat conductors.

Assumptions and Limitations
Dimensions are in meters.
Conductors are assumed to have zero thickness.
Conductors are assumed to be separated by a homogeneous medium having permittivity e=e0er and permeability u=u0.

Constants
