Magnetometer Types

Magnetometers are devices that measure magnetic fields. There are several types: 1. **Fluxgate Magnetometers** use a core material to detect magnetic changes, ideal for precise measurements. 2. **Hall Effect Magnetometers** utilize the Hall effect to measure magnetic fields; they are common in electronic devices. 3. **Optically Pumped Magnetometers** leverage atomic interactions with light to measure extremely small magnetic fields, often used in scientific research. 4. **Search Coil Magnetometers** work by detecting changes in magnetic flux, commonly used in geophysical surveys. Each type has unique applications, ranging from navigation to geological exploration and environmental monitoring.
