############################################## Gives you access to the iPhone 3GS / iPad Magnetic Field Data
#############################################

!!! NOTE: This app requires an iPhone 3GS or an iPad since it uses the 3D magnetometer hardware.

The Magnetic Data app gives you the ability to inspect and capture the iPhone 3GS / iPad magnetic field data to facilitate learning, exploration, experimentation, and analysis. The iPhone 3GS / iPad contains a 3-axis electronic compass. The hardware integrates Hall-effect magnetic sensors for detecting geomagnetism in the X-axis, Y-axis, and Z-axis. The x, y, and z magnetic data returned are measured in micro-teslas. The tesla is the standard unit of magnetic flux density.

The Magnetic Data app catures:
* The x, y, and z magnetic field readings in micro-teslas.
* Computes the resulting magnetic field data

The Info screen presents the data in real-time.

The Capture screen allows you to specify a capture rate (example 30 hertz), and the data will be captured at that rate, and stored in a file in the Flash file system. The app contains a built-in web server allowing you to download the data via wi-fi from your iPhone to a computer in a CSV file for further analysis. Multiple capture files can be created and managed. The data capture length is only limited by the free space on your iPhone.

The Library screen allows you to inspect and manage the data collection from multiple files.

Great for use for science fair projects and physics experimentation. Can measure:
- the Earth's geomagnetic fields
- local magnetic fields
- local electro-magnetic fields
- the affect of ferrous metals and how they affect the local magnetic fields

Of course, do not subject your iPhone to strong magnetic fields.
