Anomalies magnetic fields has been measured in the interplanetary space, and nearer the sun, they were interpreted as embedded solar magnetic field suggested by Parker’s theory of the solar spiral magnetic field, based on Alfvén ideas of the frozen in magnetic field; thus the extension and expansion of solar atmosphere into interplanetary space, endorsed by Pioneer V data in addition to magnetic connection, extensively dominated during the past seven decades, it shaped the current space science, although lacking convincing evidence about mechanisms of any solar phenomena; and since results derived by Pioneer V scientists was disputed, and alternative production of these anomalies magnetic fields in form of External Magnetic Field (ExMF) was suggested, therefore this session represent an outlet for different constrained hypothesis and theories to exposed its ideas about interplanetary magnetic fields and solar activities, by allowing suppressed ideas to emerged, this would bring unexpected solution to the surface.
