The invention relates to an apparatus (2) for the demagnetization and magnetic signature measurement of a stationary hull (4) and for the simulation of a magnetic field, having a demagnetization coil arrangement (8), a magnetic field sensor arrangement (10) and a simulation coil arrangement (12a, 12b, 12c) which can be positioned horizontally on one side beside the hull (4), and wherein the cross-sectional areas of the demagnetization coils (8) and of the simulation coils (12a, 12b, 12c) are arranged with horizontally oriented surface normals in the longitudinal direction of the hull (4). The demagnetization coils (8) generate an alternating magnetic field, and the simulation coils (12a, 12b, 12c) generate a stationary simulation magnetic field in all three spatial directions.
