From the early 20th century to the present, magnetometers have undergone remarkable evolution—from simple mechanical devices to highly sophisticated instruments based on advanced physics and electronics. Today, the three most widely used high‑precision magnetometers are the Proton Magnetometer, the Optically…

Introduction A Proton Magnetometer is a sophisticated geophysical instrument used to measure variations in the Earth’s magnetic field with high precision. It is widely used in mineral exploration, archaeological surveys, environmental monitoring, and engineering applications. This article explores the definition,…

I. Introduction Magnetometers have long been an indispensable tool in geophysical exploration, used extensively in mineral exploration, archaeological surveys, underground pipeline detection, and environmental monitoring. As exploration targets become increasingly complex, the demand for instruments with high sensitivity and data…

Overview：A Proton Magnetometer measures Earth’s total magnetic field by converting proton precession into a measurable frequency. The Proton Magnetometer Working Principle begins with proton polarization in a hydrogen-rich sensor, followed by free precession after the polarizing field is removed. The…
