Metal Detector: EMF Meter

Metal Detector: EMF Meter turns your Android phone into a simple magnetic field detector using the built-in magnetometer sensor.

Detect nearby magnetic metal objects, measure changes in magnetic field strength, and explore the magnetic environment around you with real-time sensor readings.

METAL DETECTOR

Use your phone's magnetic sensor to scan for nearby magnetic metals. Move your device slowly around an object or area and watch the reading change when a stronger magnetic field is detected.

EMF METER

Monitor magnetic field strength in real time. The EMF meter helps you observe changes detected by your phone's magnetometer sensor.

REAL-TIME MAGNETIC FIELD READINGS

See live magnetic field measurements while moving your phone around different objects and locations.

SOUND AND VIBRATION ALERTS

Get convenient feedback when the detected magnetic field becomes stronger, making scanning easier without constantly watching the screen.

SIMPLE METAL SCANNER

Open the app and start scanning. The simple interface makes the metal detector easy to use for everyday experiments and exploration.

USEFUL FOR

• Detecting nearby magnetic metal objects
• Finding iron and steel objects
• Exploring magnetic fields
• Monitoring magnetic field changes
• Testing magnetic objects
• Finding small magnetic items
• Educational science experiments
• Exploring your phone's magnetometer sensor

HOW DOES IT WORK?

Most modern smartphones contain a magnetometer, also known as a magnetic sensor. Metal Detector: EMF Meter reads data from this sensor and displays changes in the surrounding magnetic field.

Move your phone slowly near an object. If the magnetic field changes significantly, the reading on the detector may increase.

Results depend on your device's magnetometer hardware, sensor quality, surrounding interference, distance and the material being scanned.

IMPORTANT INFORMATION

This app detects changes in magnetic fields using the magnetometer available in supported Android devices.

Not every metal is magnetic. Non-magnetic materials may produce little or no response from a phone magnetometer.

Results can also vary between Android devices because different phones use different sensors.

This application is designed as a utility and educational tool. It is not professional metal-detection, electrical-safety or scientific measurement equipment.

Turn your Android phone into a convenient Metal Detector and EMF Meter and start exploring magnetic fields around you.
