Geo-electromagnetism

Geo-electromagnetism is the study of Earth's natural electromagnetic fields resulting from interactions between its magnetic field and electric currents within its interior. These currents, mainly in the molten outer core, generate Earth's magnetic field, which protects us from solar radiation. Additionally, natural processes like lightning and seismic activity can produce local electromagnetic signals. Understanding geo-electromagnetism helps scientists explore Earth's interior structure, monitor geomagnetic changes, and study natural phenomena affecting communication and navigation systems. Essentially, it examines how Earth's internal and surface electrical and magnetic properties interact and influence our planet's environment.
