Read full description

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.
