ABSTRACT:
A magnetic mine sweep has at least one block of permanent magnet material connected on each side in flux conducting relationship to respective distributor elements, typically of mild steel, which are secured to respective steel pipes which are closed to form cavities for providing buoyancy and for distributing the flux for mine sweeping purposes. Rigid plastic foam can be provided in the cavities for reserve buoyancy and stiffening purposes. A non-magnetic shroud extends around the block of permanent magnet material.
