magnetometer
Measures magnetic strength
A magnetometer is an instrument that measures magnetic fields—their strength, direction, or both.
Geologists use magnetometers to detect ore deposits and map underground structures.
Archaeologists locate buried artifacts.
In smartphones, a magnetometer functions as a compass.
Metal detectors at security checkpoints are a type of magnetometer, sensing the magnetic disturbance of metallic objects.
