Application sensor metal magnetometer uses magnetic sensor integrated. With the use of magnetometer it measures electromagnetic field (EMF) value in your surroundings.The actual value of the field is displayed as microtesla. Induction of the magnetic field varies from 30 to 60 microtesla (pT). If the intensity increases above 60 uT it may mean that the phone is near ferromagnetic materials (metal objects). You can try to find son in walls and metal objects underground or just prank your friends that your phone is capable of detecting the presence of a ghost;)Besides the presentation of the actual value uT, this tool shows the chart with the measurements of the last 15 seconds and shows the intensity of the minimum and maximum magnetic field. You can reset these readings any time.
Remember that this tool uses integrated magnetic field sensor. All phones are equipped with such a sensor. Please check the specifications in your phone.Measurement accuracy can be disrupted by electronic devices, such as TV or PC screen. It is preferable not to use this application around these devices. Furthermore, some cases of phone may have
