The feasibility of detecting candidate slow-rotating magnetic Ap stars with periods from a few tens of days to several hundred years is considered. The question of the fraction of objects of this kind among all Ap stars is important from the standpoint of understanding the origin and evolution of magnetic stars. The search for such objects can be based on analysis of their photometric variability using observations from the TESS space mission. For this purpose, it is first planned to examine all the objects from the corresponding catalogs. It is shown how the proposed method may be used for the example of the slowrotating Ap star HD 50169, with a detailed analysis of its variability and for which observations from the TESS mission are already available.
