Glagolevskij, E. Gerth Abstract. This is the final paper on the research of the structure of magnetic fields of stars with large periods of rotation. A preliminary conclusion is made about the absence of influence of orientation and magnetic field strength on the velocity of rotation. It is shown that the orientation of dipole structures at slow magnetic rotators is random, as well as at rotators. The hypothesis of braking the rotation of magnetic stars under the influence of magnetic fields is called in question. The origin of stars is probably connected with their initial slow rotation.
