In the presentation we discuss the formation of 1D current sheet in the course of current sheet thinning. We compare Cluster observations in the Earth magnetotail and results of laboratory experiments carried out with the device CS-3D at the Institute of General Physics in Moscow. We show that current sheets of in the Earth magnetotail and in laboratory experiments share several common properties: dimensionless spatial scales, distributions of the transverse magnetic field component along the sheet, dependence of the current density amplitude on the transverse magnetic field component. Our comparison of observed and modelled current sheets gives us an opportunity to derive several predictions about the structure and evolution of the magnetotail current sheet.
