Abstract :
This paper presents theory and validation of a numerical method based on finite elements to find magnetic anomaly due to a conductive plate in the movement in the Earth´s magnetic field. We shall use a method based on the formulation of a reduced magnetic scalar potential versus the Earth´s magnetic field (Hjφ) and an electric vector potential formulation (Tφ - φ)
