The inductor of the above tank circuit forms the detector of the metal detector (a large coil of wire). When metallic material approaches the center of the inductor (the detector coil), it enters the magnetic field created by the inductor. This changes the magnetic permeability of the inductor's core, causing the inductance to change. The ...

This metal detector, due to the use of a quartz crystal oscillator and a difference frequency signal multiplier, makes the circuit stable and extremely sensitive. Although the circuit uses five ICs, the cost is very low (30 yuan About), its use effect is no less than a few thousand yuan of ...
1. Solder Wire, Lead Free. This time I will introduce you to another extremely simple Metal Detector whose making requires only one cheap integrated circuit. The project was presented in Everyday Practical Electronics Magazine by Thomas Scarborough in June 2006. At the expense of simplicity, the results are incredibly good.
The coils for this metal detector are identical and contain about 60 turns of lacquered copper wire with a cross-sectional area of 0.4 mm^2 wound in a circle with a diameter of 15 cm. The coils are then bent and folded into a double D-shape. As I mentioned before the device is very simple to make and contains a very small number of …

A metal detector contains a coil of wire (wrapped around the circular head at the end of the handle) known as the transmitter coil. When electricity flows through the coil, a magnetic field is created all around it. As you sweep the detector over the ground, you make the magnetic field move around too.
