Magnetometer - Wikipedia
A magnetometer is a device that measures magnetism—the direction, strength, or relative change of a magnetic field at a particular location. The measurement of the magnetization of a magnetic material (like a ferromagnet) is an example.A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth's magnetic field.
