A magnetometer is any instrument that can be used to measure magnetic fields. Developments in semiconductor and microelectromechanical systems (MEMS) in the past few decades have afforded us digital magnetometers that can be used to take precise measurements of these fields. Because the Earth acts as a giant magnet, we can use magnetometers to find the direction of the Magnetic North Pole. This could be extremely useful on robots that need to determine a heading to, say, autonomously navigate a course.
