Inductance Calculator for Wire Loops
Calculates the external inductance of common wire-loop geometries and the inductance per unit length of transmission-line configurations. Each geometry includes its corresponding formula. The expressions are widely available in standard references, with many originating from F. W. Grover’s Inductance Calculations.
