Metal Detector - Magnetometer

Turn your smartphone into a powerful Metal Detector & Magnetometer using the built-in magnetic sensor. Detect nearby metals, measure magnetic field strength, and explore invisible electromagnetic forces around you with ease.

This app uses your device’s magnetometer sensor to measure EMF (Electromagnetic Field) values in real-time. Whether you're finding hidden metal objects, checking magnetic interference, or just experimenting with physics, this tool is fast, accurate, and easy to use.

🔍 Key Features

===============

📡 Real-Time Metal Detection

Detect iron, steel, and other magnetic metals instantly.

🧲 Magnetometer Sensor Readings

View precise magnetic field values in µT (microtesla).

⚡ EMF Scanner Mode

Measure electromagnetic fields around electronic devices.

📊 Live Graph & Digital Display

Visualize magnetic field changes dynamically.

🎯 High Sensitivity Detection

Works accurately depending on your phone’s sensor quality.

📱 How It Works

==============

The app reads data from your phone’s magnetic sensor (magnetometer) and converts it into a usable interface. When a metal object is near, the magnetic field value increases, helping you locate hidden objects like nails, pipes, or wires.

🧠 Use Cases

==============

Find hidden metal objects in walls

Detect electrical devices emitting EMF

Use as a simple stud finder

Learn and experiment with magnetic fields

Fun and educational tool for students

⚠️ Important Notes

======================

Requires a device with a magnetometer sensor

Works best with ferromagnetic metals (iron, steel)

Accuracy depends on hardware quality
