Wire Self Inductance Calculator

Calculate the self-inductance $ L $ using: $$ L = \frac{\mu_0 \, l}{2\pi}\left[\ln\left(\frac{2l}{r}\right) – 1\right] $$

* Enter the wire length $ l $ in meters (m) and the wire radius $ r $ in millimeters (mm). The radius is converted to meters automatically.

Step 1: Enter Parameters

Wire Length, $ l $ (m):

e.g., 1 m

Wire Radius, $ r $ (mm):

e.g., 0.5 mm (will be converted to meters)
