Inductance of Electrode or Straight Wire Calculator

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

* Enter the wire (electrode) length \(l\) and radius \(a\) in millimeters (mm). They are converted to meters automatically; the result is in microhenries (µH).

Step 1: Enter Parameters

e.g., 1000 mm (1 m)

e.g., 1 mm

Formula: $$ L = \frac{\mu_0\, l}{2\pi}\left[\ln\!\left(\frac{2l}{a}\right) – 1\right] $$
where \( \mu_0 = 4\pi \times 10^{-7} \) H/m.
