CALCULATION OF THE REFLECTION COEFFICIENT OF THE MAGNETIC FIELD VISUALIZING FILM IN THE ZONE OF DEFECTS
Methods of calculating the reflection coefficient of the magnetic field visualizing film while monitoring ferromagnetic objects are developed. Mathematical expressions are received, the analytical calculation is performed, and the change of the coefficient of light reflection from the magnetic field visualizing film in the zone of indicator pictures of integrity defects of different types is determined with consideration of their form, parameters and occurrence depth, the objects being monitored in the applied field with an external light flow directed perpendicular to the film surface.
