Quick explanation of telluric fields

Telluric fields are electromagnetic fields that occur naturally on Earth. They are generated by several sources, including the interaction of the Earth's magnetic field with the ionosphere and the electrical conductivity of the Earth's crust and mantle.

These fields are also sometimes referred to as "ground currents" or "earth currents" and can be detected by sensitive instruments, such as magnetometers, which measure changes in the Earth's magnetic field.

Telluric fields are not constant and can vary in strength and direction over time. They are also affected by various factors, such as the position of the sun and the phases of the moon, as well as geological features like fault lines and underground mineral deposits.

While telluric fields are not generally harmful to humans, they can interfere with sensitive electronic equipment, such as radio communications and power grids. Scientists study telluric fields to better understand the Earth's electromagnetic environment and to develop methods for mitigating their effects on technology.
