This EMF Detector uses your devices built in Magnetic Sensor. The sensor works by detecting magnetic fields along the x, y, and z axis or your device. The difference is that this EMF Detector displays coloured pixels on screen depending on where the magnetic field has come from and how strong the magnetic field is determines how many pixels are displayed.
