Geoelectric Field

The geoelectric field is the natural electric field present in the Earth's crust, created by interactions between the Earth's magnetic field and electrical currents within the planet. It can also be influenced by solar activity and atmospheric phenomena. This field affects how electrical signals and currents move through the Earth's subsurface, which is important for applications like fault detection, mineral exploration, and studying Earth's internal processes. Essentially, it's an invisible electrical environment within the Earth that varies over time due to natural and external factors.
