Analyzing a Free-Falling Magnet to Measure Gravitational Acceleration Using a Smartphone's Magnetometer
Pathak, Praveen; Patel, Yogita
Physics Teacher, v60 n6 p441-443 Sep 2022
A smartphone magnetometer is used to record the magnetic field of a freely falling point dipole magnet. The recorded magnetic field vs. time data are analyzed in accordance with the spatial dependence of the magnetic field to calculate the acceleration due to gravity g. The experiment gives local g to be 9.79 ± 1.9% m/s[superscript 2].
