Metal Detector: EMF Meter

Detect nearby magnetic metals and explore magnetic fields with Metal Detector: EMF Meter. Use your phone’s built-in magnetometer as a metal scanner and magnetic field meter, with live readings, sound and vibration alerts.

Scan near iron and steel objects, observe changes in magnetic field strength, and learn how your phone’s magnetic sensor responds to your surroundings.

METAL DETECTOR FOR MAGNETIC OBJECTS

Move your phone slowly near an object and watch for changes in the sensor reading. The metal detector can respond to nearby magnetic materials such as iron and steel. Detection depends on the object, distance and your phone’s sensor.

LIVE EMF METER

Explore the magnetic component of electromagnetic fields using your phone’s magnetometer. Watch magnetic field readings change as you move around objects and different locations.

This app measures magnetic fields detected by the sensor. It does not measure every type of electromagnetic radiation.

SOUND AND VIBRATION ALERTS

Receive sound and vibration feedback when the detected magnetic field becomes stronger. Follow changes in the reading without constantly looking at the screen.

SIMPLE MAGNETOMETER TOOL

Open the app and explore live sensor readings through a simple interface. Use it for everyday experiments, testing magnetic objects and learning about magnetic fields.

WHAT YOU CAN DO

• Scan near iron and steel objects
• Look for small magnetic items at close range
• Compare magnetic field readings around objects
• Observe changes in your surrounding magnetic field
• Explore how your phone’s magnetometer works
• Try educational magnetism experiments

HOW TO USE THE METAL SCANNER

1. Open the app on a phone with a magnetometer sensor.
2. Move your phone slowly near the object you want to test.
3. Watch the live magnetic field reading for changes.
4. Compare readings at different distances and positions.

Nearby magnets, electronics and other sources of magnetic interference can affect the results.

DEVICE SUPPORT AND LIMITATIONS

A built-in magnetometer is required. Performance varies with your phone’s sensor quality, the material being scanned, object size, distance and surrounding interference.

Not all metals are magnetic. Gold, silver, copper and aluminium cannot be reliably detected with this phone-based tool. It is not a gold detector or a replacement for dedicated treasure-hunting equipment.

The EMF meter reads magnetic fields only. It is not an RF detector, radiation safety meter or electrical safety tester, and should not be used to determine whether wiring or an area is safe.

Metal Detector: EMF Meter is designed for everyday exploration and educational use. It is not professional metal-detection or scientific measurement equipment.

Explore magnetic metals and discover the magnetic fields around you with your phone.
