Introduction

Magnetic methods are geophysical techniques used to study variations in the Earth’s magnetic field caused by the magnetic properties of rocks and minerals. These methods help scientists locate valuable mineral deposits, map geological structures, and study archaeological sites. Using instruments called magnetometers, magnetic surveys measure anomalies in the magnetic field, which indicate the presence of different rock types or buried objects. Non-invasive and efficient, magnetic methods are widely used in mineral exploration, environmental investigations, and even in detecting underground utilities. They provide critical insights into the Earth’s subsurface, helping us unlock its hidden features and resources.
