pin magnetic moments of electrons play a decisive role in the theory of
magnetism. Our researchhas shown, however, that this is a sadmisconception.
It turned out that in all cases, physicists deal not with the own (spin) magnetic
moments of free electrons, but with the orbital magnetic moments of electrons
associated with the atoms. The present report is devoted to the rationale for this
discovery.Тhe history of introducing the concept of electron spin is associatedwith
the Einstein-de Haas experiment on the determination of the magneto mechanical
ratio (1915). They relied on Bohr’s atomic model. From their experiment, it follows
that the ratio of the magnetic moment of an orbiting electron to its mechanical
moment exceeded in two times the expected (as followed fromcalculations) value.
Calculation of the orbital magnetic moment of an electron in a hydrogen atom
was carried out according to a simple formula: where the average value of the
electric current is produced by an electron moving in orbit was determined by the
formula, as described in all sources, including fundamental university textbooks
on physics. This was a gross mistake that we will show in this report. As turned
out, the true value of the average value of the circular current is twice as large,
namely, to compensate, thus, the lost half of the moment at the calculations, the
concept of spin of a relatively huge absolute value of, and corresponding to it, the
spin magnetic moment were introduced eventually. The opinion has fully formed
that the presence of an intrinsic mechanical moment, the spin, of an electron of
magnitude, is a real fact. However, there are no direct evidences. Information on
the determination of the spin magnetic moment on free electrons is absent
