Purpose

This application is designed to detect and analyze the presence of spinning magnets using your device's magnetometer. It's a powerful tool for hobbyists, researchers, and anyone interested in magnetic field detection.

How to Use

  1. Click the "Start the Detector" button at the top of this page to launch the app.
  2. Once in the app, adjust the frequency using the slider to set how often the sensor takes readings.
  3. Press the "Start" button to begin detecting magnetic fields.
  4. Move your device around to detect changes in the magnetic field.
  5. The app will display a real-time chart of the magnetic field strength and amplitude.
  6. Watch for changes in the amplitude to indicate the presence and proximity of a spinning magnet.
  7. The app will show you when the magnet was closest and provide a relative distance estimate.
