## What is Magna?

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.

## Key features

- AR magnetic field visualization
- Internal magnetometer data integration
- 3D mapping with ARKit
- Color-coded magnitude spheres
- Compass direction display
- Adjustable settings and color key

### 5/5 — Awesome!

*2022-05-15*

Exactly everything it ought to be- accurate and well-explained; a phenomenal app for a student of science.

## Frequently asked questions about Magna

### What is Magna-AR used for?

Magna-AR visualizes magnetic fields in real space by combining your device's magnetometer data with ARKit's 3D mapping. It overlays these visualizations onto your camera view, making it useful for STEM education and research.

### Does Magna-AR require external sensors?

No, Magna-AR does not require external sensors. It utilizes the internal magnetometer of your device to collect data and ARKit for spatial mapping.

### How does Magna-AR display magnetic field strength?

The app visualizes the total magnitude of the magnetic field at real points in space using color-coded spheres. This allows users to easily observe changes in magnitude.

### What educational benefits does Magna-AR offer?

Magna-AR is designed for students and teachers in STEM fields, helping them visualize magnetic fields from real sources rather than just computational models. It aids in understanding physics concepts related to magnetism.

### Can I see compass directions with Magna-AR?

Yes, a menu option allows you to display compass directions within the field of view, providing additional navigational context alongside the magnetic field data.

### What devices is Magna-AR compatible with?

Magna-AR is compatible with iPhones, iPads, and iPods. It requires ARKit support for its augmented reality features.

### How often is Magna-AR updated?

The latest version of Magna-AR is 2022.03.12, which was last updated on March 13, 2022. This indicates a relatively infrequent update schedule.

### What is the user rating for Magna-AR?

Magna-AR has an average rating of 3.5 stars based on 8 user ratings. This suggests a mixed reception from its user base.

## Version history (last 5 releases)

### 2022.03.12 — 2022-03-13

Fixed a bug with the compass mode.

### 2022.02.28 — 2022-03-01

Added a button to reset vector offset.
Fixed a bug that caused the app magnetic field total to freeze when the app came back to the foreground.

### 2021.09.30 — 2021-10-01

Added vector offset. You can offset the vector placement to match the location of the magnetometer.

### 2021.09.12 — 2021-09-12

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.

### 2021.01.10 — 2021-01-10

Added new setting to enable/disable camera feed.
