Abstract: | This is the final paper on a study of the magnetic field structure of CP stars with long rotation periods. It is first demonstrated
that the orientation and strength of the magnetic field have no effect on their rotation velocity. The orientation of the
dipole structures in slow magnetic rotators is shown to be random, as it is in fast rotators. The hypothesis that magnetic
stars are slowed down under the influence of the magnetic field is called into question. The origin of CP stars is probably
related to their initial slow rotation.
