The set of magnetic parameters and amplitude-frequency spectral characteristics of magnetoacoustic emission (MAE) of a large group of metal ferromagnetic materials differing in their physical properties and size are investigated. It is shown that the change in critical fields determined by the shape of the magnetization curve and the hysteresis loop of bulk samples with an increase in the annealing temperature of cold-deformed steel 20G is 1.5–3 times greater than the change in such well-known parameters for estimating the stress-strain state, such as coercive force and residual magnetic induction. It has been established that the amplitude of magnetoacoustic emission correlates with the residual magnetic induction, which makes it possible to recommend the complex application of these testing parameters in scanning systems of structuroscopy of ferromagnetic materials.
