Magnetic Field Anomaly

A magnetic field anomaly occurs when the Earth's magnetic field deviates from its usual pattern in a specific area. These differences are caused by variations in the Earth's underground composition, such as different types of rocks or mineral deposits that influence magnetic forces. Scientists detect these anomalies using sensitive instruments and analyze them to learn about subsurface structures, resources, or geological activity. Essentially, magnetic field anomalies act as clues, helping us understand what lies beneath the Earth's surface without direct excavation or drilling.
