Download or read book Eddy Current Measurement of Magnetic Flux Density written by I. R. Kraska and published by . This book was released on 1972 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of an effort to improve the reliability of magnetic particle insepection of large or irregular-shape parts by assuring optimum magnetic flux densities in the areas of interest during inspection. As assessment of flux density influence on the sensitivity of magnetic particle inspection is given. Data is provided showing eddy current response to changes in magnetic flux densities in the range of 2 to 13.5 kilogauss. This range is investigated to assure compatibility with the inspection density requirements of MIL-I-6868. This range can be changed by simple instrument adjustments. The ease of operation and excellent sensitivity fo changes in flux densities during either manufacturing or field maintenance magnetic particle inspection of irregular-shaped or large objects.
