Abstract: Our work had two objectives. First, we have extrapolated the 3D coronal magnetic field lines from MDI magnetograms for three active regions, in two different days for each one, and compared with coronal images from XRT/Hinode or EIT/SOHO. Additionally,we computed the force-free field parameter to estimate the twist in these active regions where more explosive events occurred.
