Proton Magnetometer Working Principle

Views:1     Author:Site Editor     Publish Time: 2020-12-09      Origin:Site

The principle of proton magnetometer is different from other types of magnetometers. It belongs to a branch with higher precision among many magnetometers. Even if it is used to measure weak magnetic objects, such as the earth's magnetic field, it can still obtain high resolution and precision, so it can also detect the weak changes of the earth's magnetic field.


Its working principle is based on the precession of hydrogen protons in a magnetic field. The sensor is filled with liquid containing hydrogen, and these hydrogen protons are in an irregular arrangement before being forced to polarize by the instrument. We're going to polarize it and then we're going to polarize it and we're going to spin it in. After the polarization signal disappears, the proton precession will be mainly affected by the external magnetic field, and will gradually disappear. The magnitude of the external magnetic field can be measured by measuring the frequency in the signal transmitter affected by the precession. This action can be continuously measured by cycling it.
