Physics Toolbox Magnetometer vs Imaging Stress Task

Measure, visualize, and record magnetic fields with precision — right from your iPhone. Physics Toolbox Magnetometer displays the magnetic field vector in x, y, and z dimensions along with total magnitude in microteslas (µT) or gauss, giving you the data you need for serious lab work or casual exploration. Three ways to view your data: - Chart — real-time graph with toggleable axes, adjustable line width, and fullscreen mode - Digital — large numeric readout for quick at-a-glance measurements - Compass — live heading with True North and Magnetic North display Built for the lab and the field: - Record and export data as CSV for analysis in other software - Adjustable sample rate from 1 to 100 Hz - Signal filters to reduce noise - Detects permanent magnets, electromagnetic fields, and background geomagnetic field Classroom-ready experiments: The magnetometer is well-suited for determining the inverse-square law for a point-source magnet, measuring the magnetic field produced by a solenoid, or capturing the periodic field variations of audio speakers and magnetic plate stirrers. Whether you are a physics student, teacher, engineer, or curious mind, Physics Toolbox Magnetometer turns your device into a capable scientific instrument.

Easily test the impact of time pressure and performance-related stress using adaptive math questions. The task consists of a practice phase, followed by a control phase and an experimental stress phase. After completion, results are displayed as binary values (1 = correct response, 0 = incorrect response), allowing for straightforward export and analysis in Excel or other statistical software. This app is inspired by the Montreal Imaging Stress Task (MIST) protocol as described in: Dedovic, K., Renwick, R., Mahani, N. K., Engert, V., Lupien, S. J., & Pruessner, J. C. (2005).
