MAGNETIC FIELD MEASUREMENTS AS RELATED TO INDUSTRIAL NDT APPLICATIONS

The purpose of this paper is to introduce to the nondestructive testing (NDT) engineer examples of the possible uses of magnetometer NDT techniques in his work. A brief review is made of how a typical magnetometer works. It is pointed out that magnetometer NDT applications fall into three general categories: (1) measurement of residual fields; (2) thickness measurement applications, and (3) measurement of magnetic leakage fields. Examples of these applications are presented to show that the magnetometer or similar instrumentation has a definite use and need in nondestructive testing. All of the techniques illustrated have been developed and used in industry.
