Abstract
A method of taking a plurality of measurements of the magnetic field using the plurality of sensors; includes assessing the inductive magnetic excitation; and determining the likely distribution of magnetic sources on the surface of the hull by resolving a system of equations derived from modeling the physical phenomena at play, on the basis of the plurality of measurements taken and the assessed inductive magnetic excitation. The model describes the induced magnetic sources as a distribution of dipolar sources and the remanent magnetic sources as a distribution of monopolar sources. A device (6) for determining the magnetization of the hull of a ship for implementing the method is also described.
