PCT No. PCT/FR90/00733 Sec. 371 Date Apr. 3, 1992 Sec. 102(e) Date Apr. 3, 1992 PCT Filed Oct. 12, 1990 PCT Pub. No. WO91/05739 PCT Pub. Date May 2, 1991.A process and a device for the magnetic treatment of fluid as the fluid moves in successive magnetic fields, including a sheet (1) having adjacent transverse bands (2) each of the same width (3) The bands (2) are each charged with magnets oriented alternatively NS/SN perpendicularly to the plane of the sheet so that successive transverse bands adjacent to each other present upper polar faces alternately having polarities S, N, S, N . . . S.N. Each pair of two adjacent bands being related to each other such that the width of the pair is equal to a full wavelength of alternately encountered magnetic fields with a polarity varying periodically, of which the half wave length is equal to the width of one of the adjacent bands (2) when particles (4) are circulated in a fluid relative to the bands (2) whereby relative displacement of the particles (4) with respect to the sheet subjects the particles (4) to magnetic fields which alternate in time of which the frequency increases with relative speed. The fluid is displaced in relative movement with respect to the device so that the trajectories of the particles of the fluid are substantially at right angles to the loop lines of force of the fluid, and the fields created by magnetized lines of the adjacent bands of alternate polarities are spaced apart from one another by a half wave length equal to the distance between successive N-S poles.
