Low-Frequency Magnetic Shielding
2019 IEEE International Symposium on Electromagnetic Compatibility, Signal & Power Integrity (EMC+SIPI), 2019For NASA’s Europa Clipper mission, the spacecraft is scheduled to orbit Jupiter for 3.5 years. Magnetic shielding for spacecraft electronics in this environment is challenging, mass is precious and Jupiter’s environmental magnetic fields threaten to saturate any magnetic materials on-board.

As has been demonstrated in the preceding chapters multiple pulse NMR and cross-polarization of dilute spins are the most prominent techniques for evaluating the chemical shielding tensor σ of nuclei in solids. Other methods for determining parts of the chemical shielding tensor like the “second moment” analysis, the NMR of partially oriented molecules

Concrete for magnetic shielding
Cement and Concrete Research, 1995The use of steel paper clips in the amount of 5 vol.% in concrete was found to result in concrete with magnetic shielding (60 Hz) ability comparable to steel mesh. Furthermore, the paper clips did not affect the compressive strength of the concrete. The paper clips were discontinuous enough for mixing with the concrete mix, while their intertwining ...

Magnetic Shielding (Shielding of Magnetic Instruments From Steady Stray Fields)
Transactions of the American Institute of Electrical Engineers, 1929This paper is a brief survey of the vast amount of work on magnetic shielding of instruments against steady stray fields, and allied problems, by several authors during the last fifty years. It contains, first, a simplified presentation of the method of zonal harmonic analysis, by way of introduction to the mathematical theory of shielding as presented

Magnetic shielding for magnetically levitated vehicles
Proceedings of the IEEE, 1973The magnetic shielding required for magnetically levitated vehicles is discussed. Shielding is needed to protect passengers in a vehicle from stray dc magnetic fields coming from the superconducting dipoles carried by the vehicle. In addition, the superconducting dipoles must be shielded against various ac magnetic fields. Here we consider shielding of

Opened-type magnetic shielding
Digest of INTERMAG 2003. International Magnetics Conference (Cat. No.03CH37401), 2004In this paper, we describe the efficiency of magnetic shielding doesn't become worse at the area of 1m far from magnetic shielding wall in the case that there are some opening space between the magnetic materials ( "opened-type" ). Also we report the basic charecteristics about this opened-type magnetic shielding on the basis of two-dimensional ...

As the number and magnitude of radiated electromagnetic fields from electronic devices increase, the radiation of electromagnetic field must be carefully considered because it can cause physiological harm on human body. It may also lead to malfunctioning of other electronic systems.
