Metal Detector is an Amazing tool that uses magnetic sensor to find the

metal surrounding you.

Metal detector measures nearby electromagnetic fields using the phone's

built-in magnetometer compass. The magnetic field level(EMF) in nature is

about 30~60μT(microtesla) or 300~600mG(milligauss); 1μT = 10mG.

If there is any metal in the area, the strength of the magnetic field

should increase.

The accuracy of metaldetector depends entirely on the sensor in your

device. Note that the magnetic sensor is affected by electronic equipment

(TVs, PCs, etc.) due to electromagnetic waves.

How to use: Open this app on your device, and move it around. The magnetic

field values will constantly fluctuate. That's it!
