Magnetic Flux Leakag Technique used to Pipeline Defect Detection with Finite Element Method

Abstract

The work present the numerical modeling of defect detection in a pipeline using magnetic flux leakage technique. The problem is consisting on resolution of a 2D magnetostatic equation by considering an exciting coil as source excitation field and then a permanent magnet. A comparison between results is performed for the different source fields. The results obtained seems to be acceptable when comparing with those provided in literature.
