About Magna-AR
This app combines the data collected by the internal magnetometer with the three-dimensional mapping of ARKit to plot magnetic fields in real space superimposed upon the camera view.
Useful for students and teachers in science, technology, engineering, and math (STEM) education and academic or industrial researchers, this app helps users to visualize magnetic fields based upon real sources—not prepared computational models—without the use of external sensors.
The actual total magnitude of the magnetic field at real points in space can be visualized with color-coded spheres to see changes in magnitude. A menu allows the user to learn more about the operating principles of the magnetometer, display compass directions in the field of view, and change settings to display/remove magnetic field values and modify the color key.

New tare feature. (accessible by tapping the total magnetic field value)
Enabling \'Tare\' will measure the average background magnetic field (strength and direction), and subtract it from measurements and visualizations. Taring is useful for visualizing local magnetic fields, such as around a magnet, without the interference of background fields.
