CrowdMag: Your Smartphone's Gateway to Earth's Magnetic FieldDiscover the power of your smartphone with CrowdMag, a unique Android application that transforms your device into a scientific instrument. CrowdMag empowers you to measure and understand the Earth's magnetic field, contributing to valuable research while exploring the world.
Key Features:
* **Flight mode: Turn Your Flights into Scientific Expeditions.** Contribute to scientific research by measuring the magnetic field during your flights. Simply input your itinerary, and CrowdMag will allow you to collect data as you travel. For detailed instructions, see the tutorial at https://www.noaa.gov/education/resource-collections/data/tiny-tutorials/crowdmag-flight-mode.
* **Comprehensive Magnetic Field Measurement:** CrowdMag measures the Z (downward component), H (horizontal intensity), and F (total intensity) magnetic field components, providing detailed insights into the local magnetic field.
* **Data Visualization and Analysis:** View your data as interactive graphs and maps, displayed in nanotesla units. Analyze your measurements and gain a deeper understanding of magnetic field variations.
* **Create and Share "Magtivities":** Record magnetic data during your outdoor activities, such as walks or runs, and save them as "magtivities." Share your findings with NOAA (optional) to contribute to scientific understanding.
* **Data Management and Backup:** Easily export your data as a CSV file and create backups to ensure your measurements are safe. Import your data to new devices without losing your progress.
* **Magnetic Calculator:** Access a built-in magnetic calculator that provides magvar (declination), dip angle, total magnetic field, and other components based on the latest World Magnetic Model (WMM2020).
* **Interactive Compass:** Utilize a live magnetic compass that shows both true and magnetic north, with 2D and 3D rendering options and optional audio output.
* **Customization Options:** Customize recording frequency and location accuracy to fit your needs, and access generalized crowdsourced magnetic data from other users.
* **Data Export and Sharing:** Export your data via email, Google Drive, or other options.
* **Stay Updated:** View information about the current solar magnetic disturbance.
CrowdMag is more than just an app; it's a tool for scientific exploration. Whether you're a science enthusiast, a researcher, or simply curious about the world around you, CrowdMag provides a powerful and accessible way to study Earth's magnetic field.
