The electromagnetic wave experiment for CSES mission: Search coil magnetometer
Science China Technological Sciences, 2018The 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 ...

Noise calculation and analysis of a search coil magnetometer
2010 International Conference on Computer Application and System Modeling (ICCASM 2010), 2010For 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.

Research of Core Characteristics of Search Coil Magnetometer
Advanced Materials Research, 2012In 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.

Frequency response of search coil magnetometer with magnetic feedback
2010 International Conference on Computer Application and System Modeling (ICCASM 2010), 2010Search 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.

Analytical Optimization of Low-Frequency Search Coil Magnetometers
IEEE Sensors Journal, 2012An 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 ...

Development of Micro-size Search Coil Magnetometer for Magnetic Field Distribution Measurement
Journal of Magnetics, 2008 For the measurement of the magnetic field distribution with high spatial resolution and high accuracy, the magnetic field sensing probe must be non-magnetic, but the MFM probe and sub-millimeter-meter size Hall probe use a ferromagnetic tip and block, respectively, to increase the sensitivity. To overcome this drawback, we developed a micro-size search
