This article explores the magnetic field sensor embedded in mobile phones, and presents some ways to use it together with straightforward software applications. Measurements are processed with features such as averages, georeferencing coordinates, data exporting, visualization, etc, by means of an open-source tool. Covering the hardware part, the sensor magnitude calibration and also its frequency response are discussed. All materials and elements are affordable and easily available. Results show the high potential of its use in class and also for research applications.
