Summary

The subject creates the theoretical aspects of magnetic field, specifies the magnetic properties of materials, analyzes the influences of materials and bodies defects on magnetic properties of these materials and bodies. The one of the main parts describes the measurement techniques and the principles of magnetic inspection. The computer modeling is included too.
