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.

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 ...

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 ...

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.

The RPW/Search Coil Magnetometer onboard Solar Orbiter [PDF]

, 2019
Measuring the fluctuating magnetic fields associated to various phenomena such as waves, shocks, and turbulence is essential for the Solar Orbiter mission. These measurements rely on a tri-axial Search Coil Magnetometer (SCM) built at the Laboratoire de Physique et Chimie de l'Environnement et de l'Espace (LPC2E) in Orléans, France. Two antennas of SCM

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.

First results from the SCM search-coil magnetometer onboard Parker Solar Probe [PDF]

, 2018
The SCM search-coil magnetometer measures AC magnetic fields with three components from 10 Hz to 50 kHz, and one component from 1 kHz to 1 MHz. The instrument was designed to properly observe the turbulent cascade of the solar wind in the inertial range and at kinetic scales, whistler waves and their role in the evolution of the electron distribution ...

"Observing Dissipation Scale Dynamics of the Inner Heliosphere with Merged Search Coil and Fluxgate Magnetometer Measurements" [PDF]

, 2019
The Parker Solar Probe (PSP) mission serves as an opportunity to understand the connection between turbulent dissipation and particle heating and solar wind acceleration. Though inherently connected to plasma kinetic scales, the physical dynamics and in-situ observational signatures of dissipation typically depend on macroscale properties of the mean ...

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 ...
