Magnetic memory testing is a new nondestructive testing technique. It has the incomparable advantages of traditional nondestructive testing technique, and can find the stress concentration of ferromagnetic materials. In this paper, the development of magnetic memory testing is analysed, and the problems encountered in the development of magnetic memory is studied. The research on magnetic memory mainly focuses on the following three aspects, study on the mechanism of mechanical magnetic coupling, analysis of external influence factors of signal and extraction of damage evaluation parameters. Finally, in the paper, the development direction of magnetic memory testing in the future is summarized. That is, to strengthen the research on the micro mechanism of magnetic memory and to establish the correct mechanical magnetic coupling model.
