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.
