Geomagnetic Fields, Magnetite, and Neural Behavior: A Physics-Based Approach

The physics of magnetoreception remains largely unexplored, with increasing evidence linking geomagnetic fluctuations and magnetite (Fe₃O₄) to neural activity. This study investigates the interaction between geomagnetic fields and biological systems by exposing C. elegans to Earth-strength magnetic field variations within a controlled Helmholtz coil setup. Four experimental conditions—control, magnetic field exposure, magnetite bath, and combined exposure—allow for the analysis of locomotion dynamics, directional bias, and clustering. Real-time tracking and computational modeling quantify these effects, testing whether geomagnetic interactions induce neurodegenerative-like behaviors through biophysical mechanisms. By integrating geomagnetism with neurobiology, this research explores fundamental questions in field-matter interactions, biological magnetosensitivity, and potential implications for human neurological health.
