The following is a design tool which calculates the inductance of an air core . Diameter and length of inductor are entered in millimetres along with the number of turns. Enter L, l and Wire Gauge (all four are required) to calculate multilayer inductor data.
The Coilprogram is coil inductance calculator, that computes: one-layer and multi-layer air core inductors, coils on ferrite rings, on the pot core, flat coils on . Learn how to wind your own Inductor using thick copper wire for a low resistance coil. Use this online calculator to determine the inductance of single-layer and multilayer air-core coils. Both metric and English units of measurement are supported.
Enter your values: Coil Diameter: inches. As the title indicates, this page is for the design of a single-layer, air-core, coil. UHF range but only as a basis for further calculation and experimentation. Formula used in this calculation is from Wheelers approximations which is accurate to if the cross section is near square shaped.
