The rigid body - a sphere of a mass of 98.3% and of a diameter of 70% - gets the positive and negative charges from the core as an electric map (+++++ on this border). The granules (ovals) rotate on this sphere of 70% . They pick up these charges of the map and copy it on the surface as Xerox-cylinders. The positively charged whirls (on the right) produce northern (N) poloid field according to the right hand rule. The surface emits these charges: the negative areas ( Italy and Anti-Italy) as solar wind, the positive areas (+++++++) as coronal loops. Italy ( above) rotates rigidly because it is only the copy of a DEEP-ITALY which lies on the border of the rigid body. DEEP-ITALY is continually fed by the thermoelement-electrons from the core.
