Description

MagneticField combines two free apps to collect and analyze magnetometer data.

File data collected by 'Physics Toolbox Magnetometer' app is transformed to Excel spreadsheet 'MagneticField/copy.xls' using the template spreadsheet 'MagneticField/input.xls'. The selected magnetometer data is fit to a curve and displayed with the the fitted curve.

The template file can be edited to perform other analysis functions but note that columns 1-8 will be over-written by data.

The following are recommended apps for collection and analysis.
