EMF Detector detects Electromagnetic Field and Magnetic Field strength near electrical and magnetic devices using built in device magnetometer. Reading has been shown in Micro Tesla (ÂµT).Uses:* EMF Detector helps you detect electric field near electronic devices.* EMF Detector detects magnetic field around a device.* Metals can be detected using this app.* People asks what is a normal emf reading for a house, normal readings are around 49T(micro tesla) or 490mG(milli gauss) where 1T = 10mG* Can be used as EMF field Strength Meter* Measure EMF in your home and around devicesFeatures:* Beep sound when values are higher* Beep sound on/offNote:This app uses magnetic sensor in mobile device. Mobile devices having no sensor should not install this app. You can install it to verify if you have magnetic sensor in your device or not.
