The Kinematical Features of a Force-Free Magnetic Field

  • In this paper, the kinematical features of an axial-symmetric force-free magnetic field are discussed. It is generally believed that the energy may be stored in the active region by twisting the potential magnetic field into the force-frec magnetic field by current. The analysis shows that this process is impossible if the magnetic field is regular at the symmetric axis.
