G-862 CESIUM
Geometrics G-862 magnetometer produces a Cesium Larmor frequency output at 3.498572 Hz per nT. 'nT' refers to the magnetic field strength as measured in nanoTesla. 1 nT equals one gamma or 10-5gauss. So, at the earth's surface, in a nominal 50,000 nT field, the Larmor frequency is about 175 kHz.

The cesium magnetometer uses an atomic resonance of the Cs 133 atom (see note 1 below) which varies proportional to the ambient magnetic field. This atomic resonance is used to set/control the frequency of an oscillator. Therefore the output signal from the magnetometer is a *frequency* which is proportional to the earth's magnetic field at a ...
