Application "metal detector pro" uses built-in magnetic sensor. With the use of magnetometer it measures electromagnetic field (EMF) value in your surrounding metal detector apps .
Actual value of the field is displayed as microtesla detector . Induction of Earth's magnetic field ranges from 30 to 60 microtesla (µT). If the intensity increases above 60 µT it may mean that the telephone is near to ferromagnetic materials (metallic objects). with this apps magnetic You can try to find wires in the walls and metallic objects under the ground or simply share info with your friends that your phone is able to detect presence of a metal ghost detector ;)
how to use this apps :
magnetic Beside presenting actual µT value, this tool displays the chart with the measurements of metal the last 15 seconds and presents minimum and maximum magnetic metal field strength. You can reset those readings any time detector .
Remember that this tool detector uses built-in magnetic field sensor . Not all phones are equipped in such a sensor metal apps . Please check it in your phone specification detector .
Accuracy of measurements can be disturbed by electronic devices, such as TV set or a PC screen detector. It's better not to use this application around such devices apps .metal Additionally some phone cases may have magnetic detector apps
