Magnetometer

maker

A magnetometer is a scientific instrument used to measure the strength and direction of magnetic fields.

expanded

Magnetometers are used in various applications, ranging from geological surveys to consumer electronics, to detect and measure magnetic fields. These devices are crucial in applications such as navigation, where they assist in determining orientation by sensing the Earth's magnetic field, and in industrial contexts for non-destructive testing and material characterization.

examples

The Geometrics G-858, a cesium vapor magnetometer, is used for archaeological surveys to detect sub-surface artifacts by measuring anomalies in the Earth's magnetic field with sensitivity up to 0.005 nT (nanotesla).

Commonly used in fields like archaeology and geology, the G-858 helps identify areas of interest by observing variations in the magnetic field that may indicate buried features.

The Bartington MAG-03 range of fluxgate magnetometers provides three-axis magnetic field measurement and is often used in industrial and environmental monitoring with a range of ±100 μT to ±1000 μT (microteslas).

These fluxgate magnetometers are widely used in environmental monitoring to characterize electromagnetic interference and magnetic disturbances in the industrial environment.
