Physics Toolbox Magnetometer

This magnetic field sensor app displays Magnetic Field (µT) in x, y, z dimensions, as well as total magnitude.

This is the first release of the app for iOS. On an upcoming update the option to Record a cvs file and a graph will be added.

The magnetic field sensor can measure the background magnetic field of the earth and be used to check for the presence of permanent magnets or electromagnetic fields. Within the classroom, the magnetometer can be used to determine the inverse-square law for a "point source" magnet, to determine the strength of a field produced by a solenoid, or to measure the frequency of objects with magnetic variations, such as audio speakers or magnetic plate stirrers.
