The working of metal detector depends on the mechanism of an electromagnet electromagnet.
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.
The magnetic field disappears when the current is turned off.
Electromagnets are widely used as components of other electrical devices, such as motors, generators, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment.

The basic working principle of metal detector is electromagnetic induction.
Explanation:
- The basic working principle of metal detector is transmitting a magnetic field to the object of study and analysing the signal which is returning from the target.
- The magnetic field of the object of interest induces an electromagnetic field in the metal object and induces an electromagnetic field in the secondary which as a result makes a beeping sound in the detector.
- These principle of electromagnetic induction is used in detecting and studying the presence of metals underground.
- This instrument is used by archaeologists and also security purpose and military people.
