		| Abstract: | 
		In some stars we observe changes of the magnetic phase curve with time, which means that the parameters of the magnetic field change. Such changes occur in some objects on a time scale of several years, which is several orders of magnitude faster than what is predicted by theory. These changes create a need for the improvement of the theory of magnetic field evolution. |
