electromagnetic methods

Electromagnetic methods are techniques used to study the Earth's subsurface by measuring how it responds to electromagnetic fields. In these methods, energy is transmitted into the ground, and the way the ground materials—like rocks and minerals—alter this energy helps scientists infer their composition and structure. These methods are widely used in fields like geology, environmental studies, and resource exploration, including oil, gas, and minerals. They provide valuable information without the need for extensive excavation, making them essential for mapping and assessing natural resources and subsurface conditions.
