Today, surface ships and submarines are made of ferromagnetic material, so they are easily being "seen" by the enemy while operating on the sea. Therefore, the study of methods and techniques for analyzing, identifying and eliminating magnetic traces is a top urgent mission. The determination of the magnetic traces for ships is actually a complicated task and consumes large computational resource. Consequently, equivalent models with structures reflecting to the shape of the actual hull are studied. For that purpose, the paper will focus on spherical hull models using combination of three methods: analytic, finite element and semi-analytic calculus. The obtained results give preliminary assessments on magnetic characteristics and trends; evaluate effectiveness and applicability in magnetic detection and magnetic silencing studies for surface ships and submarines.
