Operating principle<\/h3>\n

Firstly, the operation of a metal detector depends on technology called pulse induction<\/i> (PI).<\/p>\n

By sending out a current pulse, the transmitter coil creates a magnetic field around the coil.<\/p>\n

When this magnetic field comes into contact with a metal object, it induces an electric current in it, thus creating a secondary magnetic field.<\/p>\n

The metal detector then perceives this new magnetic field and emits a beep.<\/p>\n
