# Air Core Inductor Calculator

Online electrical calculator to calculate the inductance of an air core inductor coil. Enter the value for the diameter of the coil, its length and the number of turns to get the desired result. The air core coil with an inductor does not depend upon a ferromagnetic material to achieve its specified inductance. This air core inductor calculator will be useful when making an antenna matching units, crystal sets, antenna traps, or anywhere where an air cored single layer inductor is required.

**Formula:**
Inductance = (d^{2} x n^{2}) / ((18 × d) + (40 ×l))
** Where,**
d = Coil Diameter (inch)
l = Coil Length (inch)
n = Number of Turns
