  The magnetic disturbances are associated with electric currents as it is well
checked at laboratory room scales and described by the Maxwell's equations of
electromagnetic field. The analysis of spacecraft observations for more than a
quarter of a century failed to provide a self-consistent three-dimensional
picture of the solar wind-magnetosphere dynamo generated magnetospheric and
ionospheric current systems. The proposed solar wind and the interplanetary
magnetic field (IMF) driven reconfiguration of the earth's magnetosphere
directly accounts for the observed magnetic disturbances. So role of the
magnetospheric currents in creation of the magnetic disturbances is
reconsidered in accordance with some poorly understood observations. A
quantitative agreement with observations is demonstrated and a laboratory
experiment to test the suggested model of the solar wind/IMF-magnetosphere
interaction is described.
