Use Your Device to Detect Magnetic Fields. With this app you can detect wood studs hidden under walls, drywall, plasterboard, or stucco. Magnetic Detector uses your device's compass (magnetometer) sensor to precisely detect metal studs, nails, screws, and other metal fasteners embedded in all wooden wall studs. This app operates in a similar manner to other hand-held stud detector tools: as you move the device along the wall, the needle will move and a beep can be heard. Magnetic Detector is an application which detects the presence of metal nearby by measuring the magnetic field value. This tool uses the magnetic sensor built-in your mobile device and shows magnetic field level in μT (microtesla). The magnetic field level (EMF) in nature is about 49μT(micro tesla) or 490mG(milli gauss); 1μT = 10mG. If any metal is near, the value of magnetic field will increase. Metal Detector allows to identify any metal object in area, because all metals generate magnetic field which strength can be measured with this tool. Features: - Automatic sensor that measures the magnetic field in uT. - Active detection beep. - You can save the time when the measure is taken. Download now!
