Magnetometer

What is it ?
magnetometer is a device used to measure magnetic fields. There are several types of magnetometers, each with different characteristics and uses. Smartphones use Hall effect magnetometers, which measure the deflection of an electric current passing through a plate in the presence of a magnetic field. The stronger the magnetic field, the more current is deflected. Common magnetometer uses include: - land and sea navigation using the earth's magnetic fields to determine direction - geological surveys to measure magnetic fields associated with rocks and minerals - analysis of magnetic properties of materials for industrial applications such as electric motors, permanent magnets and data storage devices - scientific research to study magnetic phenomena in the natural environment, such as the aurora borealis and solar storms.
