Анотация: Summary: Previously experimental studies of higher harmonic components of magnetic induction showed, that when a ferromagnetic sample is magnetized by a constant magnetic field and simultaneously is remagnetizated by a "weak" alternating field, the resulting minor hysteresis loop is asymmetric. The form of the branches of such cycle corresponds to the quadratic parabola, as well as at symmetric Rayleigh's loop. In this article it is shown mathematically that in such asymmetrical minor loop reversible component of magnetization changes according to the parabolic law. The irreversible component of the magnetization changes in this case along a symmetric minor loop. In symmetrical Rayleigh's minor loop, as is known, reversible component is a linear function of the strength of external magnetic field.
