Magnetometry in Space Exploration

Key Engineering Materials, 2015
Magnetometry in space exploration is a field utilizing physical laws of magnetism and electromagnetism, which studies the magnetosphere of planets and their possible satellites in order to map the planetary or interplanetary magnetic fields and to extract information on the structural composition of the planets (targeting mining mapping) and the ...

Advances in Fluxgate Magnetometry for Space Physics

2017
Fluxgate magnetometers are an essential tool for solar-terrestrial research and monitoring or forecasting space weather. They provide high precision measurements of the Earth’s magnetic fields and can be used to infer the currents that transport energy and momentum through the magnetosphere and ionosphere.
