How Do Metal Detectors Work?
A metal detector is used for detecting the presence of metals in areas or objects. It does this by utilizing a special type of device called an inductive coil, in combination with a powerful magnetic field, to create a detectable signal when it comes into contact with a metal material.
The inductive coil transmits alternating current through it and this produces a powerful magnetic field that reaches out and interacts with any metallic objects close by. When the magnetic field of the inductive coil encounters something metallic, it causes eddy currents to be generated within the object. These eddy currents produce an electrical charge that is then detected by the metal detector and displayed on its screen.
The sensitivity of the metal detector also affects its detection range as well as how deep beneath the surface it can detect metals. Metal detectors come in various shapes, sizes, and levels of sensitivity so that they can be tailored for different applications. With proper care and maintenance, your metal detector will have many years of reliable service!
