This paper presents the development of a portable probe for detecting cracks in steel plates. The probe consists of a magnet and a giant magneto-resistance (GMR) sensor. The magnet provides a radial magnetization at the surface of the steel plate. The GMR sensor detects the tangential component of the magnetic flux leakage due to a crack in the steel plate.(More)
In this paper, theoretical bases for the development of a software for electromagnetic effects simulation based on the approximation method of finite differences using Scilab are presented. A methodology for programming the algorithm is discussed and a simulation test is conducted in order to validate it, which consists of a coil with a ferromagnetic core.(More)
