Parallel Wire Inductance Calculator

Parallel Wire Inductance Calculator

Estimate the inductance using: $$ L = \frac{\mu_0 \, l}{\pi}\ln\!\left(\frac{D}{r}\right) $$

* Enter the wire length \(l\) in meters (m), the center-to-center spacing \(D\) in millimeters (mm), and the wire radius \(r\) in millimeters (mm). The calculator converts mm to m automatically.

Step 1: Enter Parameters

e.g., 1 m

e.g., 10 mm

e.g., 1 mm

Formula: $$ L = \frac{\mu_0 \, l}{\pi}\ln\!\left(\frac{D}{r}\right) $$
