A Free Android App to Measure the Strength of the Magnetic Field

EMF (Electromagnetic Field) is the phenomenon caused by the presence of an electrical current and/or voltage in the environment. This field can be measured with an EMF detector. The human body, houses, and other objects create an EMF. However, most of the time, this field is too small to be detected by conventional measuring devices.

Metal Detector is a free Android app that allows you to use the device’s magnetic sensor to measure the strength of the magnetic field and turn your device into a real metal detector. This app can be used as a body scanner, emf meter, wires finder, pipe finder, or even a ghost finder.

The strength of the magnetic field depends on the type of metal, its concentration, and the distance between the device and the target. For example, a person living near a metal source will have a higher magnetic field reading than someone living far away.

If you have a strong suspicion that there is a metal present, you should get a stronger reading than the one shown in the app.
