Also known as a digital compass or magnetic sensor, a magnetometer is a device that measures the intensity and orientation of the earth's magnetic field. A magnetometer can be as simple as a compass or as sophisticated as a vector helium magnetometer, an instrument used on spacecraft. For certain industries, magnetometers are necessary because the degree of magnetism on the earth’s surface can differ depending on location.

What Small and Midsize Businesses Need to Know About Magnetometer

Typically, magnetometers are used in airport security systems, archeology, and mineral mining. They are also widely used in technology such as mobile devices, particularly in apps on smartphones and tablets that access or require user location. To support business applications, researchers are developing magnetometers that can shrink hard disk drives while increasing their data storage capacity.
