WebFeb 1, 2001 · Birkeland Current. Birkeland currents, that connect the magnetospheric particle distribution to the ionosphere, are calculated from the Vasyliũnas equation (1970) (4.16)J∥i=12bˆ⋅∇iV×∇ipwhere the subscript (i) refers to gradients computed in the ionosphere, bˆ is the unit vector of the magnetic field, and p is the particle pressure.
