windingturns

Single-layer and multilayer winding calculator using the Wheeler formula. Enter diameter, length (and depth for multilayer) then either the number of turns or the target inductance -get whichever you didn't enter, plus the wire length to cut.

Air-Core Coil Designer — Multilayer winding

Air-Core Coil Designer — Single-layer winding

How to use

Two modes — Single layer / Multilayer.

What it's for

Single-layer or multilayer air-core coil: turns ↔ inductance from the geometry (Wheeler).

You enter

Coil diameter and length, winding depth for multilayer, then either the turns or the inductance you want.

You get

Whichever you didn't enter, the nearest whole turn, mean diameter, pitch per turn, and the wire length to cut.
