Magnetometers

Magnetometers are sensors that detect and measure magnetic fields, including Earth's magnetic field. They are used in various applications like navigation (e.g., smartphones and ships), detecting underground metal objects, and scientific research. Essentially, a magnetometer senses changes in magnetic forces and converts that information into an electrical signal, allowing devices to determine direction, position, or the presence of magnetic materials. Their sensitivity enables them to distinguish subtle differences in magnetic fields, making them valuable for precise location tracking and environmental monitoring.
