Apparatus (14, 14a) for treating liquids flowing through a pipe (10, 10a) is formed by clamping magnet units (16) of the desired number to the pipe (10, 10a). The magnet units (16) are formed by permanent magnet structures (20) held in a plastic casing (18) by a potting compound (36). The permanent magnet structure (20) includes two pairs of permanent magnets (24, 26, 28, 30) having first surfaces (24N, 26N, 28S, 30S) projecting beyond the potting compound (36) and the open side (18d) of the casing (18) and second surfaces (24S, 26S, 28N, 30N) directly abutting with the upper surface of a ferromagnetic strip (22) providing a flux path between the second surfaces (24S, 26S, 28N, 30N) of the permanent magnets (24, 26, 28, 30). The magnet units (16) are clamped so that the first surfaces (24N, 26N, 28S, 30S) of the permanent magnets (24, 26, 28, 30) directly bear against the outside of the pipe (10, 10a). The first surfaces (24N, 26N, 28S, 30S) of the permanent magnets (24, 26, 28, 30) are physically configured to have a more intimate contact with the pipe (10, 10a) to overcome the loss of effectiveness experienced when the pipe (10, 10a) is formed of magnetic material.

[ What is claimed is:] [1.] Apparatus for magnetically treating a liquid flowing through a pipe comprising, in combination: a casing having an open side; at least first and second permanent magnets in the casing, with the first and second permanent magnets being spaced a distance in a longitudinal direction, with each of the permanent magnets having oppositely directed first and second surfaces providing first and second poles, with the first surfaces of the permanent magnets being flat and residing in one plane, with the first surfaces of the permanent magnets having a length in the longitudinal direction and a width; a ferromagnetic strip having a length equal to the combined lengths of the first surfaces of the first and second permanent magnets and the distance therebetween, with the ferromagnetic strip confronting the second surfaces of the permanent magnets and extending between the first and second permanent magnets; potting compound in the casing, with the first surfaces of the permanent magnets extending beyond the open side of the casing and also projecting beyond the potting compound for directly bearing against the outside of the pipe having the liquid to be treated flowing therethrough; and means for clamping the casing to cause the first surfaces of the permanent magnets to directly bear against the outside of the pipe.
