Metal Detector: Magnetic Scan

Metal Detector uses your phone's built-in magnetic field sensor (magnetometer) to find nearby magnetic metal such as iron and steel. HOW IT WORKS • Tap the glowing dial to start a scan, then move the top edge of the phone slowly near an object. • The gauge shows the magnetic field in microtesla (µT) and how much it changes. • Sound and vibration get faster as the field changes more. • Pick Low, Normal or High sensitivity to suit your phone. • Tap "Calibrate here" to reset the baseline at your current spot. • Tap the dial again to stop and see the peak reading, then scan again from another spot to compare. GOOD TO KNOW • It reacts to magnetic metals like iron, steel, nickel and magnets. It cannot detect gold, silver, copper or aluminium. • Detection range is a few centimetres and depends on your phone's sensor. • Keep the phone away from magnetic cases and electronics for best results. Works offline. Needs a phone with a magnetic sensor.
