- Title
Different remanence states and their resistance to external effects. Discussing the so-called magnetic memory method.

- Abstract
The remanence of a ferromagnet is formed under the influence of many factors, the main ones being a magnetic field (DC and AC), temperature, mechanical stress and chemical transformations. Remanences obtained by different methods are resistant to external influences in different ways. The remanence observed in structural elements may result from one factor or from all of the above. It is shown that the use of remanence as a parameter for assessing the stress-strain state, ie the so-called magnetic memory method, without taking into account the conditions of the formation of the remanence state in a product area under testing will have low assessment reliability.
