✦ Synopsis


An elementary analysis based on Amp6re's Law is given to separate the general magnetic field above the photosphere into two parts B = BI + B*. The field B1 is a potential field due to electric currents below the photosphere. The field B* is produced by electric currents above the photosphere combined with the induced mirror currents. By symmetry, B* has a set of field lines lying entirely in the plane z = 0 taken to be the photosphere. This set of field lines can be constructed from given vector magnetograph measurements and represents all the information on the electric currents above the photosphere that a magnetograph can provide. Theoretical illustrations are given and the implications for data analysis are discussed.

The gross-structure of the force-free currents in the solar atmosphere and their possible dynamics have been discussed as caused by quasi short-circuited electric fields, generated by the motion of the solar magnetic features.

Neutral current sheets are expected to form in the solar atmosphere when photospheric motions or the emergence of new magnetic flux causes oppositely directed magnetic fields to he pressed together. Magnetic energy may thus be stored slowly in excess of the minimum energy associated with a purely po
