Inductance Calculator

Calculates the external inductance of various wire loop configurations and the inductance per-unit-length of various transmission line geometries. Formulas are provided for each configuration. These formulas can be found in various texts and most of them are derived in the book "Inductance Calculations" by F. W. Grover.

External Inductance of Wire Loops

Select the box with the loop geometry that you would like to evaluate. The calculator determines the external inductance of the loop.

Inductance per Unit Length of Transmission Line Geometries

Select the box with the transmission geometry that you would like to evaluate. The calculator determines the external per-unit-length inductance.
