Frequency response of search coil magnetometer with magnetic feedback

2010 International Conference on Computer Application and System Modeling (ICCASM 2010), 2010
Search coil magnetometer is widely used in Magnetotellurics (MT) to measure weak magnetic field. In our design, magnetic feedback is used to flatten the frequency response near the resonance. We proposed a new model to investigate the system frequency response.

Noise calculation and analysis of a search coil magnetometer

2010 International Conference on Computer Application and System Modeling (ICCASM 2010), 2010
For expertise on detecting very weak signal, search coil magnetometer is widely used in Magnetotellurics (MT). Unfortunately, noise is a primary factor affecting the sensitivity. In this work, noise model of the magnetometer is presented based on measured parameters, where transfer function affected by core eddy current loss is considered.

The electromagnetic wave experiment for CSES mission: Search coil magnetometer

Science China Technological Sciences, 2018
The seismic activities on the Earth can produce a disturbance of the electromagnetic field and particles in the ionosphere. The search coil magnetometer (SCM) mounted on China Seismo-Electromagnetic satellite (CSES) is designed to measure the magnetic field fluctuation of low frequency electromagnetic waves in the frequency range of 10 Hz – 20 kHz ...

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.

Increasing the Sensitivity of Search Coil Magnetometer by Capacitive Compensation

IEEE Sensors Journal, 2016
This letter proposes a compensation method that aims to increase the sensitivity of search coil magnetometers. The method is based on internal capacitive compensation of the magnetic devices, which enables to increase the device resonance frequency, without reducing the number of turns. The method is verified theoretically and tested experimentally.

Simulation Analysis of Micro Coils for the Fabrication of Micro-scaled Search Coil Magnetometer

2016 International Conference on Computer and Communication Engineering (ICCCE), 2016
Magnetic field detection has been widely accepted in many applications such as military systems, outer space exploration and even in medical diagnosis and treatment. Low magnetic field detection is particularly important in tracking of magnetic markers in digestive tracks or blood vessels.

Fluxgate and Search Coil Hybrid: A Low-Noise Wide-Band Magnetometer

IEEE Transactions on Magnetics, 2012
We propose a new hybrid magnetometer that operates in a wide frequency range from dc to over 30 kHz and has a very high resolution. It is made in a coaxial structure by combining a pT-level fundamental mode orthogonal fluxgate and a search coil magnetometer.

Improvements on the Design of Search Coil Magnetometer for Space Experiments

Sensor Letters, 2007
Search coils despite of their bulk, are still used on space experiments thanks to their ability to measure weak magnetic fields and also to their robustness. This paper will focus on the search coil modeling and design. We propose an original shape of the magnetic core allowing an improvement of their performances.

The Search-Coil Magnetometer onboard the ESA JUICE mission

2020
<p>The JUpiter ICy moons Explorer (JUICE) mission is the first large-class (L1) mission in ESA Cosmic Vision. JUICE is planned for launch in 2022 with arrival at Jupiter in 2029 and will spend at least four years making detailed observations of Jupiter’s magnetosphere and of three of its largest moons (Ganymede ...

An optimized low-frequency three-axis search coil magnetometer for space research

Review of Scientific Instruments, 2005
The design of a three-axis search coil magnetometer in the 1 Hz–20 kHz range developed for the scientific satellite DEMETER is described. The sensitivity is a critical parameter as the search coil must be able to detect very weak signals in the Earth’s magnetosphere.
