flanges to one another connecting means 50 may be any means known in the art to connect flanges 54 and adjust the distance between them in fig2 the magnetic field 52 may also be seen it forms a y shape in the middle of conduit 51 and because of the bidirectional nature of the three magnets the generated magnetic fields form a pair of loops about the device this draws the emanated field closer to the device and prevents spreading of the magnetic field very far from the device itself this also serves to strengthen the field that is applied to conduit 51 although the field applied to the conduit is not expressed as a straight line but rather a v shaped field those skilled in the art will appreciate that this is essentially unidirectional those skilled in the art will also appreciate that this design ensures that all of the fluid and all of the regions of the conduit are exposed to a magnetic field of sufficient strength because the externally projecting energy of the magnets is drawn back into the device by exterior opposing poles this field is even stronger fig3 shows a diagrammatic front view of an alternative embodiment of the present invention in this particular embodiment magnets 68 are all aligned in the same direction such that the same poles on each of them face conduit 70 focusing strips are also shown focusing strips 62 are located on sidewalls 64 of casing 66 as can be seen.
