Magnetic connection on the back side

Magnetic connection on 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. Electrified material is accelerated away from this disturbance (thick arrows), both away from the Earth and back toward it.
