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.

What is Metal Detector Coil and How Does it Work? MEGA LOCATORS

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?

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.

COIL SIZES. The size of a coil can influence the detection depth and sensitivity of a detector. The larger the coil, the deeper it tends to detect, but will have less sensitivity to small targets. The smaller the diameter, the more sensitive it becomes, but with reduced detection depth. Smaller coils will also be lighter in weight, easier to.
