Turns your cell phone into a metal detector.
This app measures magnetic field value using the built-in magnetic sensor that is built into your device. The magnetic field level(EMF) in nature is about 49μT(micro Tesla) or 490mG(milli gauss); 1μT = 10mG. The magnetic field in nature ranges from 25 to 65 µT (0.25 to 0.65 G).
If there is any metal in the area, the strength of the magnetic field should increase. Sometimes, this app used to find electrical wires in walls (like a stud finder) and iron pipes in the ground.
1 Green : Magnetic field level in nature within tolerance.
2 Yellow : Magnetic field level is medium, you are not far to find a metal object.
3 Red : Magnetic field level is too high, there is a metal object nearby. If the value is too high, device will vibrate, which means that metal object is detected.
How to use:
Open this app on your device, and move it around. The magnetic field level will constantly fluctuate. That's it!
The accuracy depends entirely on the sensors in your device.
App works best detecting ferromagnetic materials, such as iron and can’t detect non-ferromagnetic materials such as aluminium.
If this app does not work properly, it may mean that your phone's sensors are damaged, broken or non-existent. To initialize the sensors, point your phone up towards the sky and move it in a figure 8 pattern. Especially, a view cover with a magnet or a leather case with a magnetic snap can cause unwanted results.
Magnetic sensor is affected by electronic equipment (TVs, PCs, etc.) due to electromagnetic waves.
