Abstract (en)
[origin: EP0356146A2] A magnet assembly comprises a rigid non-magnetic frame (10) which can be located around a vessel such as a submarine. Embedded in the frame (10) is a plurality of magnetic elements (12), suitably variable magnetic moment magnets. A plurality of magnetic sensors (13) is mounted rigidly on the frame (10) but spaced from it, and control means are provided for controlling the magnetisation state of the variable moment of magnets according to the magnetic field detected by the magnetic sensors. The magnetic signature of the submarine can thereby be reduced to a minimum.
