Eddy Current Measurement of Magnetic Flux Density.

Abstract

The report presents the results of an effort to improve the reliability of magnetic particle inspection of large or irregular-shaped parts by assuring optimum magnetic flux densities in the areas of interest during inspection. An 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. (Author Modified Abstract)
