Turn Your Smart Phone Into A Metal Detector

[HandmadeCreativeChannel]

This application measures the magnetic field with a built-in magnetic sensor.
The level of the magnetic field (EMF) in nature is about 49μT (micro tesla) or 490mG (milli gauss); 1μT = 10mG. When a metal (steel, iron) is close, the level of the magnetic field will increase.

The use is simple: open the application and move it. The level of the magnetic field will constantly fluctuate. It is! You can find electrical wires in the walls (like a spike detector) and iron pipes in the ground.

Many ghost hunters had downloaded this app and experimented as a ghost detector.

The accuracy depends entirely on your magnetic sensor (magnetometer). Note that it is affected by electronic equipment (TV, computer, microwave) due to electromagnetic waves.

I never knew phones could do this.
