Short summary

We performed a theoretical study of how the Earth’s ionosphere interacts with the tenuous magnetosphere above it. We asked the following: what leads to electric fields and electric currents flowing between these two regions? We concluded that one source of currents flowing between these regions is the localized heating of neutral gas by energetic particles precipitating from above (the magnetosphere).
