build your own metal detector - All About Circuits

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,

Simple Metal Detector Circuit Diagram using 555 Timer IC

The figure shows the circuit diagram of metal detector. The 555 IC timer here acts as a square wave generator and it generate pulses with frequencies audible to human. The capacitor between pin2 and pin1 should not be changed as it is need to generate audible frequencies.
