abstract = "One of the most important processes that occurs in Earths
magnetosphere is known as magnetic reconnection (MR). This process
can be symmetric or asymmetric, depending basically on the plasma
density and magnetic field in both sides of the current sheet. A
good example of symmetric reconnection in terrestrial
magnetosphere occurs in the magnetotail, where these quantities
are similar on the north and south lobes. In the dayside
magnetopause MR is asymmetric, since the plasma regimes and
magnetic fields of magnetosheath and magnetosphere are quite
different. Symmetric reconnection has some unique signatures. For
example, the formation of a quadrupolar structure of Hall magnetic
field and a bipolar Hall electric field that points to the center
of the current sheet. The different particle motions in the
presence of asymmetries change these signatures, causing the
quadrupolar pattern to be distorted and forming a bipolar
structure. Also, the bipolar Hall electric field is modified and
gives rise to a single peak pointing toward the magnetosheath,
considering an example of magnetopause reconnection.",
