Definitions

  • inventive embodiments are also discussed in the descriptive section of the present application.
  • inventive content may also consist of several separate inventions, especially if the invention is considered in the light of expressions or implicit subtasks or from the point of view of advantages or categories of advantages achieved. In this case, some of the attributes contained in the claims below may be superfluous from the point of view of separate inventive concepts.
  • FIG. 3 shows a pressure arrangement 40 having two ferromagnetic dies 42, 44 of a different size.
  • the upper die is slightly larger than the lower die. This leads to a convergent orientation of the magnetic moments of the domains in the magnetic material 20.
  • the course and direction of the magnetic flux lines are indicated with lines 29 and arrows.
  • the coils 26, 36 are preferably arranged to surround the pressure chamber completely. They may surround the pressure chamber 24 only partially and may extend only along a part of the axial length of the pressure chamber 24.
