摘要：
Computational electromagnetics is used to study, design and optimize electromagnetic instruments. This paper introduces function of a magnetic instrument, namely, instrumented pipeline inspection gauge (IPIG), and various computational methods useful for its analysis. Usage of FEMLAB for detailed understanding of magnetic flux leakage (MFL) phenomenon both in 2D and 3D finite element analysis (FEA) is explained. It finally presents a method to perform an important step of defect characterization for IPIG by building large database using FEA tool.
