Description
This application is considered a fun application and must not be used in critical situations.
There is a number of so-called Metal Detectors out there in the market. This is often irritating since the phone's magnetic sensor reacts on magnetism rather than on metals. Some metals, however, carry a magnetic field, such as a pair of scissors or a screw driver.
Gold and silver do not assume magnetism in that an application like this is not capable of detecting treasures.
However, the Android magnetic sensor, if incorporated, is well capable of detecting objects, such as loudspeakers, cell phones, refridgerators and anything that contains magnetism.
Not all Android phones employ the same magnetic hardware sensor, in that sensitivity and accuracy may vary by manufacturer. Some devices do not provide a magnetic sensor at all.
The application computes the total magnetic field, TMF, magnitude from rectangular XYZ components by squaring:
TMF = Sqrt(X*X + Y*Y + Z*Z) [μTesla]
A few field tests resulted in positive detection of magnetized objects, such as pipes, drum cans, scoops, fences, etc. However, what is the purpose of scanning objects that can be seen and touched? A real-world test should involve detection of objects buried underground or in a wall.
Anyway, please try it yourself. If it won't work for you it will at least guide you to the location of the magnetic sensor in your phone - if it has one. Designed for phones in portrait mode only. No ads!
