The Earth is a dynamic planet with complex systems operating far beneath its surface. Among these systems, the magnetic field plays a crucial role in shielding our planet from harmful solar radiation, while also guiding navigation through its fluctuations and anomalies. Recent research has unveiled the existence of two enor...
