| Zusammenfassung |
| We investigate Cluster observations of strongly tilted sheets
(flapping events) in the magnetotail.
In accordance with the simple model of
slip deformation (vertical differential displacement of
neighboring flux tubes), the Jy current density component
in the tilted sheet remains constant and equal to that in the
horizontal undisturbed sheet. However, a substantial Jz component
appears proportional to the local sheet tilt.
Slip-type variations, having smaller scale than the full crossing,
locally change the tilt and Jz and may thus create a variety
of non-classical (bifurcated, asymmetric etc) current density profiles. |
