Magnetometers, which measure the strength and direction of magnetic fields, have a diverse range of applications across various industries. Archaeologists utilize magnetometers to detect buried structures, as magnetic anomalies indicate the presence of ferromagnetic materials. Geologists harness magnetometers to study the Earth’s magnetic field, gaining insights into tectonic plate boundaries and mineral exploration. Engineers employ magnetometers in navigation, ensuring precision in aircraft and marine equipment. Additionally, medical practitioners leverage the sensitivity of magnetometers in magnetoencephalography (MEG), which maps brain activity by measuring magnetic fields emitted by neurons.
