OGO Search Coil Magnetometer Experiments

IEEE Transactions on Geoscience Electronics, 1969
The OGO triaxial search coil magnetometer measures naturally occurring magnetic fluctuations between 0.01 Hz and ~1000 Hz in the space around the earth. The instrument design is described and the design rationale discussed. The results of the observations on the first five OGO spacecraft in the magnetosphere, magnetotail, magnetosheath, and ...

Research of Core Characteristics of Search Coil Magnetometer

Advanced Materials Research, 2012
In this paper, the theory of apparent permeability and effective permeability of the core is described. The apparent permeability with coil in different positions of the core is investigated and simulated by HFSS. The best location of the coil is determined according to the curves of the apparent permeability.

Analytical Optimization of Low-Frequency Search Coil Magnetometers

IEEE Sensors Journal, 2012
An analytical optimization is proposed for the sensitivity threshold of low-frequency search coil magnetometers employing disk-shape flux concentrators. The optimal diameters of the core and the wire are found for a given set of the optimization parameters: frequency, search coil volume and aspect ratio, relative permeability of the core and the flux ...

Simplified Design of a Low Frequency Search Coil Magnetometer

2019 11th International Symposium on Advanced Topics in Electrical Engineering (ATEE), 2019
The paper describes in detail the process of designing a magnetometer with induction coil and ferromagnetic core. This includes the analysis of core material parameters and the effect of heat treatment upon the magnetization characteristic, the choice of core dimensions based on the minimization of the demagnetization factor, determining the coil ...
