👉 Insweeping is a technique used in the field of geophysics and remote sensing to detect and analyze the variations in magnetic fields or other electromagnetic fields that exist at a given location. This involves using radar, satellite imagery, or other high-resolution imaging techniques to identify and measure these variations. The goal is to understand the structure and composition of the Earth's interior, as well as its geologic history, through the study of the variation in the magnetic field due to different conditions such as temperature fluctuations
