Every day, the bicentennial anniversary of Ampere's famous mistake made in interpreting the experimental result of Oersted (1821) is getting closer. This mistake distorted the true understanding of the nature of magnetism. Because of her, physics still naively considers magnetism not independent, but a secondary phenomenon originating from electricity. The falsification of the nature of magnetism led to a distortion of the quantitative characteristics of the intrinsic magnetic fields of electrons, neutrons and protons, to the refusal to take into account the magnetic interactions between micro-objects in the theory of the microworld in physics and in chemistry, and to the loss of the ability to use Newton's quantitative formalism in studies of the structures of atoms and other objects of the microworld ... Thus, Ampere's mistake caused serious damage to the achievement of true ideas about the structure of material objects of the micro- and macrocosm. Physics has not yet been able to correct this Ampere's mistake. The theory of nonlinear oscillations had to deal with its correction. Some of these fixes are summarized below.
