Magnetometer: EMF & Metal

Magnetometer is a magnetic field meter, metal detector, and EMF detector for Android. Using your phone's built-in magnetometer sensor, it measures magnetic field strength in µT (microtesla) in real time and turns your device into a pocket teslameter and EMF meter.

▶ MAIN FEATURES

• Magnetic field strength in µT (microtesla) and mT

• Live metal detector – sweep your phone to find hidden metal

• EMF / electromagnetic field meter for appliances and wiring

• X / Y / Z axis readout plus total magnitude

• Adjustable alarm threshold with sound and vibration alert

• One-tap calibration for accurate readings

• Max hold to capture peak values

• Real-time graph and measurement history

• Dark mode for comfortable viewing

• Works fully offline – no internet required

▶ HOW TO USE

1. Open the app and hold your phone steady to calibrate.

2. Watch the live µT reading on the main display.

3. Slowly move your phone near objects, walls, or wires.

4. A rising value and the alarm reveal magnetic fields or metal.

▶ WHO USES IT

• Find hidden metal, nails, pipes, and magnets inside walls

• Check EMF from appliances, chargers, and household wiring

• Hikers and campers calibrating a compass in the field

• Science teachers and students exploring magnetism

• Ghost-hunting hobbyists logging field fluctuations

• Makers and DIY builders testing magnets and motors

This app uses the magnetometer sensor already in your phone, so results depend on your hardware. Keep your phone away from speakers and strong magnets while calibrating for the most accurate magnetic field readings.
