Circular Loop Inductance Calculator

Circular Loop Inductance Calculator

Calculate the inductance \( L \) using: $$ L = \mu_0 R \left[\ln\!\left(\frac{8R}{a}\right) – 2\right] $$

* Enter the loop radius \( R \) and conductor radius \( a \) in millimeters (mm). They will be converted to meters automatically.

Step 1: Enter Parameters

e.g., 50 mm

e.g., 1 mm

Formula: $$ L = \mu_0 R \left[\ln\!\left(\frac{8R}{a}\right) – 2\right] $$
where \(R\) and \(a\) are in meters and \(\mu_0 = 4\pi \times 10^{-7}\) H/m.
