Kids' Basics: Metal Detector DIYODE Magazine

The part of this circuit that makes it work as a metal detector is the group of components formed by the 2.2μF and 4.7μF capacitors, the coil of wire, and the 51kΩ resistor. In particular, the 2.2μF capacitor and the inductor formed by the coil of wire will oscillate as current flows into the capacitor.

How Metal Detectors Work HowStuffWorks

Since most metals vary in both inductance and resistance, a VLF metal detector examines the amount of phase shift, using a pair of electronic circuits called phase demodulators, and compares it with the average for a particular type of metal. The detector then notifies you with an audible tone or visual indicator as to what range of metals the
