The caesium and potassium magnetometers are typically used where a higher performance magnetometer than the proton magnetometer is needed. In archaeology and geophysics, where the sensor sweeps through an area and many accurate magnetic field measurements are often needed, caesium and potassium magnetometers have advantages over the proton ...
A vibrating-sample magnetometer (VSM) (also referred to as a Foner magnetometer) is a scientific instrument that measures magnetic properties based on Faraday’s Law of Induction. Simon Foner at MIT Lincoln Laboratory invented VSM in 1955 and reported it in 1959. [ 1 ]
Magnetometers for non-space use evolved from the 19th to mid-20th centuries, and were first employed in spaceflight by Sputnik 3 in 1958. A main constraint on magnetometers in space is the availability of power and mass. Magnetometers fall into 3 major categories: the fluxgate type, search coil and the ionized vapor magnetometers.
More exceptionally, magnetometers are used for low-resolution exploratory surveys. Several types of magnetometer are used in terrestrial archaeology. Early surveys, beginning in the 1950s, were conducted with proton precession magnetometers. Data collection with proton precession instruments was slow, making high sample density surveys ...

SERF magnetometers measure magnetic fields by using lasers to detect the interaction between alkali metal atoms in a vapor and the magnetic field. The name for the technique comes from the fact that spin exchange relaxation , a mechanism which usually scrambles the orientation of atomic spins , is avoided in these magnetometers.
It had a caesium vapor scalar magnetometer and a fluxgate vector magnetometer. [7] CHAMP , a German satellite, made precise gravity and magnetic measurements from 2001 to 2010. [ 8 ] [ 9 ] A Danish satellite, Ørsted , was launched in 1999 and is still in operation, while the Swarm mission of the European Space Agency involves a "constellation ...
This instrument measures the fine structure of the interplanetary magnetic field, mapped the Jovian magnetic field, and provided magnetic field measurements to evaluate solar wind interaction with Jupiter. The magnetometer consists of a helium-filled cell mounted on a 6.6 m boom to partly isolate the instrument from the spacecraft's magnetic field.
