Metal Detector EMF detects the presence of metal nearby. Metal detectors measure magnetic field value using a magnetic sensor that is built into your smartphone. Now You can easily find metallic objects that are hidden underground, behind walls etc. , or be a treasure hunter or ghost hunters, also see a reading trend through the graph. Simple app in your device called Gauss Meter are used for measuring the Earth's magnetic field but can't detect silver, gold, copper coins (non-ferrous - no magnetic field). This Magnetometer app require a magnetic sensor otherwise does not work.
µMagnetometer
Measures the strength of the magnetic field around you using your device's magnetometer. Requires Location Services to be enabled on iOS. Provides microtesla readings for nearby magnetic fields.
- Measures magnetic field strength
- Displays readings in microteslas
- Utilizes device magnetometer
- Requires Location Services (iOS)
