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 ...

Initial results from the search coil magnetometer at Siple, Antarctica

Journal of Geophysical Research, 1975
Micropulsations were observed at Siple, Antarctica, throughout 1973. The results of this brief examination of the data generally agree with previous studies. The search coil magnetometer used is most sensitive in the Pc 1 frequency range, where its sensitivity approaches the natural background noise.

A portable low noise low frequency three-axis search coil magnetometer

IEEE Transactions on Magnetics, 1980
The design of a three-axis search coil magnetometer is described which has noise characteristics that are close to or better than comparable superconductor magnetometers over the 20Hz to 2000Hz range. The sensor coils and electronic conditioning equipment weighs less than 14Kg and can be transported by one person in a 46cm × 46cm × 15cm instrumentation
