Such coils are often used as induction sensors for metal detectors. This coil is an outstanding representative of short coils and this coil cannot be calculated by the empirical Wheeler's formula for multilayer coil. What is the way out? Firstly, you can apply a numerical method of calculation according to Maxwell's formula.
How to Test your Metal Detector Coil? (Simple Tips) Detecting School
In short, a search coil is the component of a metal detector that transmits the magnetic field generated by the detector into the ground. It also detects the signals created by interactions with the magnetic field and communicates those signals back to the control box for processing. How does a Search Coil Work?

Understanding Metal Detector Coils Search Coil Basics Gear Up.
The concept is simply a clear and concise answer to metal detecting questions that come up in the hobby it is designed that the listeners can dip in and out when there is a question being discussed that they are interested in.
What is Metal Detector Coil and How Does it Work? MEGA LOCATORS
This calculator help for you to estimate the number of turns of your home-brew one-layer R.F. inductor or choke on the design stage. The calculator uses Bob Weaver's equation with round wire corrections. The Coil32 for Android and the cross-platform Coil64 makes it possible to calculate the self-capacitance and Q-factor of the single-layer coil.
Transformer winding and Calculation Step by Step YouTube
"Coil64" is a free coil inductor calculator, that allows calculating: single-layer and multilayer air core inductors, toroidal air core coil inductance, inductors on ferrite rings, in pot core, flat coils on the PCB, and also LC tank parameters. The program has additional plugins to calculate another manner of coils.
Calculate the Inductance of Coil YouTube
So for metal detector coils we can use the universal algorithm for calculating a multi-layer coil, based on the Maxwell coaxial circular filament method. But since the cross section of the winding is square and the thickness of the coil is much smaller than its diameter, we can use a simplified calculation.
