Measurements of the Net Charge Density of Space Plasmas [PDF]
Journal of Geophysical Research: Space Physics, 2021 Abstract Space plasmas are composed of charged particles that play a key role in electromagnetic dynamics. However, to date, there has been no direct measurement of the distribution of such charges in space. In this study, three schemes for measuring charge densities in space are presented.
