Metal detector on Windows Pc

now any metal including gold and silver with your mobile phone.
do you now your mobile has a built in magnetic censure to measure the magnetic field.
A metal detector is an instrument that detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. They often consist of a handheld unit with a sensor probe which can be swept over the ground or other objects. If the sensor comes near a piece of metal this is indicated by a changing tone in earphones, or a needle moving on an
indicator. Usually the device gives some indication of distance; the closer the metal is, the higher the tone in the earphone or the higher the needle goes. Another common type are stationary "walk through" metal detectors used for security screening at access points in prisons, courthouses, and airports to detect concealed metal weapons on a person's body. The main types of metal detectors are, beat-frequency oscillation, very low frequency, pulse induction and industrial.
Metal Detector allows to identify any metal object in area, because all metals generate magnetic field which strength can be measured with this tool.

Usage is quite simple: launch this application on your mobile device and move it around. You will see that the magnetic field level shown on screen is constantly fluctuating. Colorful lines represent the three dimensions and the numbers on top shows the value of magnetic field level (EMF). The chart will increase and the device will vibrate and makes sounds announcing that metal is close. In settings you can change the sensitivity of
vibration and sound effects.

You might use the Metal Detector it to find electrical wires in walls (like a stud finder), iron pipes on the ground... or pretend it's a ghost detector and scare someone! The accuracy of tool depends entirely on the sensor in your mobile device. Please, note that due to
electromagnetic waves, the magnetic sensor is affected by electronic equipment.

Metal detector cannot detect gold, silver and coins made by copper. They are classified as non-ferrous that has no magnetic field. But maybe you will find metal box with some treasure inside!
