In this talk, I will introduce the concept of magnetic reconnection in plasmas. It will be discussed
in which physical environments magnetic reconnection can occur: form black holes to the laboratory,
passing through magnetic fusion devices. It will be shown how kinetic e ects can be retained in the
quest for a physically reliable description beyond magnetohydrodynamics, for quasineutral [1, 2, 3, 4,
5] and electron-positron plasmas [6, 7]. Finally, the most recent, analytical [8, 9] and computational
[10] studies of magnetic reconnection in Wendelstein 7-X will be presented.
