Abstract

The article considers the dependences of the formation of the indicator pattern on the calculated magnetization mode of the object of control and the concentration of magnetic powder. The features of the choice of the magnetization method are described. The magnetic characteristics on which the calculated current depends are determined. Formulas for calculating the set current are given to ensure the required value of the magnetic field on the surface of the controlled part. An illustrative experiment was conducted showing the importance of observing the required concentration of magnetic powder.
