A magnetometer is a tool or instrument that measures the magnetization of an item or the force of a magnet. The magnetometer typically looks at the Earth's magnetic field and local magnetic field in order to determine the location and vector of a magnetic force.Why is a magnetometer important?
Magnetometers are widely used for measuring the Earth's magnetic field, in geophysical surveys, to detect magnetic anomalies of various types, and to determine the dipole moment of magnetic materials. In an aircraft's attitude and heading reference system, they are commonly used as a heading reference.What are magnetometers used for?
Magnetometers are used in geophysical surveys to find deposits of iron because they can measure the magnetic field variations caused by the deposits, airplanes like the Shrike Commander has been used . Magnetometers are also used to detect archaeological sites, shipwrecks and other buried or submerged objects.What is fluxgate magnetometer?
A fluxgate magnetometer is a device that measures the intensity and orientation of magnetic lines of flux .
