Proton magnetometer - Wikipedia
网页A proton magnetometer, also known as a proton precession magnetometer (PPM), uses the principle of Earth's field nuclear magnetic resonance (EFNMR) to measure very small variations in the Earth's magnetic field, allowing ferrous …
Magnetism: Notes: Proton Precession Magnetometer
网页For land-based magnetic surveys, the most commonly used magnetometer is the proton precession magnetometer. Unlike the fluxgate magnetometer, the proton precession magnetometer only measures the total size of the Earth's magnetic field. These types of measurements are usually referred to as total field measurements.

Proton Precession - an overview | ScienceDirect Topics
网页2000年7月15日 · A typical example of scalar magnetometers is the proton-precession magnetometer. In this magnetometer, a strong field is applied to protons (which are in the molecules of water contained in the cylinder) and afterward removed.
Proton Magnetometer - SpringerLink
网页2021年1月1日 · Proton precession magnetometer. Category: Tool. Definition: An instrument used in magnetic surveying for detecting changes in magnetic field intensity; it takes intermittent measurements of absolute field strength. The detector consists of a bottle of alcohol or water around which is wound an electrical coil of 1,000 turns.
Proton-precession magnetometer | measurement instrument
