Earth currents, also known as telluric currents, are natural electrical currents that flow through the Earth. These currents are generated by various factors, including the Earth's magnetic field, solar activity, and atmospheric conditions. They can travel through the ground and are often influenced by geological formations and moisture levels in the soil. These currents can be detected using sensitive instruments and are important for understanding the Earth's electrical environment. They play a role in various natural phenomena, such as lightning and geomagnetic storms, and can also affect communication systems and navigation technologies.
