  • Patent number: 11535351
    Abstract: A device (2) for demagnetizing and for measuring the magnetic signature of a stationary hull (4) and for simulating a magnetic field, including a demagnetization coil assembly (8), a magnetic field sensor assembly (10) and a simulation coil assembly (12a, 12b, 12c), which can be positioned next to the hull (4) in a horizontal manner on one side and the cross-sectional areas of the demagnetization coils (8) and of the simulation coils (12a, 12b, 12c) being disposed in the longitudinal direction of the hull (4) with horizontally oriented surface normals. The demagnetization coils (8) produce an alternating magnetic field; the simulation coils (12a, 12b, 12c) produce a stationary simulated magnetic field in all three dimensions.

  • Publication number: 20210241961
    Abstract: A coil system (30, 40, 50) for generating a homogeneous magnetic field, includes a coil assembly (2), each assembly having at least two coils (S1, S2, S3), the respective windings (W1, W-2, W3) of which span. rotationally symmetrical faces lying plane-parallel to one another having different sizes and a common axis of rotation running perpendicularly to the faces, forming a coil axis (4), wherein a current can flow in the opposite direction through at least one of the coils (S1, S2, S3), and having at least two coil assemblies (2), wherein the coils (S1, S2, S3) of each coil assembly (2) are located within and oriented plane-parallel to the base of a generating pyramid, the tip of which coincides with the centre of a regular convex polyhedron and the base surface of which is identical to one such face of the convex polyhedron, on which the projection of the pyramid tip onto the pyramid base surface coincides with the centre of the pyramid base surface.
