Magnetic field mapping is the process of visualizing the strength and direction of magnetic fields in a given area. This is often done using tools like magnetometers that measure the magnetic field's intensity and orientation. The data collected can be represented in various forms, such as contour maps or 3D models, helping scientists and engineers understand how magnetic fields interact with their environment. This technique is widely used in various fields, including geophysics, engineering, and environmental science. By mapping magnetic fields, researchers can identify geological formations, locate buried objects, or assess the impact of magnetic fields on electronic devices.
