A magnetometer is an instrument used to measure the strength and direction of magnetic fields. It is commonly employed in various fields, including geophysics, geology, archaeology, and space exploration, as well as in navigation systems, such as those found in smartphones and aircraft. There are different types of magnetometers, including: 1. **Fluxgate Magnetometers**: These measure the vector components of magnetic fields with high sensitivity and are often used in research and industrial applications.
