Testing of mechanical stresses in steel shafts by means of the magnetic method is proposed in the article. This method is referred to nondestructive methods. The growth and concentration of mechanical stresses result in micro-cracks and their enlargement. Further growth of micro-cracks can lead to a severe accident - damage to the shaft. Replacing of the shaft is a very expensive operation. The authors propose a testing and monitoring method based on the dependence of the ferromagnetic material magnetic properties on mechanical stresses.
