The possibility of a pinchlike concentration of magnetic flux produced by the generation of electric currents in the solar atmosphere is studied. To isolate this effect from other evolutionary effects, the evolution of axisymmetric force-free fields due to pure rotational shearing motions is studied. It is shown that concentration of magnetic flux to the axis can be achieved by such shearing motions, with density enhancement in higher layers. This may give rise to localized high-density flux concentrations in the chromosphere and corona, containing strong magnetic fields and electric currents. The dissipation of these currents causes localized heating, which may explain the observed close correlation between flux concentrations and temperature and density enhancements in the chromosphere and corona.
