Magnetometer

A magnetometer is a device that detects and measures magnetic fields, including Earth's magnetic field. It helps determine direction and location, functioning like a compass but often with greater sensitivity. Magnetometers are used in navigation systems, mineral exploration, and scientific research to study magnetic properties of materials or to detect underground objects. They work by sensing changes in magnetic forces and translating those into readable signals, providing critical data for applications that require precise magnetic measurements for orientation, mapping, or detection purposes.
