Formation of current sheets in 3D magnetic fields with a null point
Bogdanov S. Yu., Burilina V. B., Markov V. S., Frank A. G.
It has been established experimentally, for the first time, that current sheets can form in 3D magnetic configurations containing a null point. A smooth change in the angular orientation of the current sheet has been observed in the transition from a 2D configuration with a null line to various 3D magnetic configurations. It is shown that current sheets can form under conditions such that the electric current is flowing perpendicular to the separatrix plane.
