Measurements of the magnetic moment of a ship are necessary for monitoring safety from magnetic mines and from stealth, by the magnetic field. A modification of the method of measuring the magnetic moment of a ship by using a three-component differential magnetometer is examined. With the aid of computer modeling, a comparison was done of the errors of the method developed by the authors with those of known analogs, and its advantage in precision (by practically one order of magnitude) was established. It is shown that the proposed method can be applied also to magnetic models of ships and standard samples of magnetic materials in order to determine the components of hysteresis loops by magnetization.
