Magnetic Connection the Back Side

Magnetic Connection the Back Side

. The Sunís wind brings solar and terrestrial magnetic fields together on the night side of Earthís magnetosphere, in its magnetotail. Magnetic fields that point in opposite directions (thin arrows), or roughly toward and away from the Earth, are brought together and merge, reconnecting and pinching off the magnetotail close to Earth. Material in the plasma sheet is accelerated away from this disturbance (thick arrows). Some of the plasma is ejected down the magnetotail and away from the Earth, while other charged particles follow magnetic field lines back toward Earth.
