By using the Stud Detector-Wall Stud Finder Appon your Android phone, you can find any metal such as gold and silver (rings, bangles).
Detecting lost gold rings and bangles was a concept only using mobile phones. Now women can use this brand new gold and metal detector tool to find their precious gold and jewellery.
This app measures magnetic fields with a fixed magnetic sensor.
The magnetic field level (EMF) in nature is about 49T (micro tesla) or 490mG (milli gauss); 1T = 10mG. When any metal (steel, iron) is near, the magnetic field level will increase.
The free Gold Detector helps to identify any metal object in its surroundings because all metals generate a magnetic field whose strength can be measured with this tool.
How does a Stud Detector-Wall Stud Finder work?
As we know, when electricity current flows through the transmitter coil, it creates a magnetic field all around it. If you sweep the metal detector above a metal object, the magnetic field penetrates right through it. The magnetic field makes an electric current flow easily and quickly inside the metal object.
