to investigate the relation between photospheric horizontal plasma motion and the evolution of chromospheric and coronal plasma and magnetic field, 3D MHD simulation was performed.This simulation uses a potential extrapolation of the line-of-sight(LOS) component of the observed photospheric magnetic as initial condition. For instance, we took the magnetic field associated to an EUV BP observed on 2006 December 19 by Hinode. The influences of different velocity patterns on the generation of electric currents are investigated.
