Physics Toolbox Magnetometer

This magnetic field sensor app, the Physics Toolbox Magnetometer, is a must-have for anyone interested in measuring and understanding magnetic fields. Whether you are a student, a teacher, a researcher, or simply curious about the world around you, this app offers a range of features to explore and analyze magnetic fields.

Key Features:

• Measures and displays a graph of Magnetic Field (µT) vs. Time (s) in x, y, and/or z dimensions


• Displays total magnitude of the magnetic field


• Data can be displayed with a digital read-out


• Records and exports total magnitude magnetic field strength via e-mail or Google Drive as a .csv attachment


• Customizable settings for data plotting and collection rate


• Brief tutorial for app usage

Practical Applications:

Within the classroom or in research settings, the Physics Toolbox Magnetometer can be used for various purposes, including:

• Determining the inverse-square law for a "point source" magnet


• Measuring the strength of a field produced by a solenoid


• Identifying the frequency of objects with magnetic variations, such as audio speakers


• Checking for the presence of permanent magnets or electromagnetic fields

Permissions Explained:

The app requires the android.permission.WRITE_EXTERNAL_STORAGE permission to create and modify a .csv file on the phone's internal memory.
