A magnetism applying circuit, which has a construction in which the different polarity ends of a pair of permanent magnets are connected to the respective ends of a yoke having a V-letter shape, is attached to a pipe so as to place the permanent magnets close to the pipe. Therefore, a magnetic fluid treatment apparatus which can reduce magnetic field leakage is formed. |

DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings, the following description will discuss various embodiments of the present invention.
FIG.
2 is a cross-sectional view of the first embodiment of the present invention showing the construction of a magnetic fluid treatment apparatus.
FIG.
2 shows the lateral cross-section of a water supply pipe W made of iron in the center, and indicates a state in which a fluid treatment apparatus 1 is attached on the peripheral face of the water supply pipe W.
The fluid treatment apparatus 1 is provided with two magnetism applying circuit units 10a and 10b, an opening engaging plate 20, and a sliding engaging plate 30.
The two magnetism applying circuit units 10a and 10b, which are aligned face-to-face with each other, have the same construction; therefore, an explanation will be given only of one of the magnetism applying circuit units 10a, and an explanation of the other magnetism applying circuit unit 10b is omitted.
A pair of permanent magnets 11a and 11b are attached to the respective ends of a yoke 13a made of iron, having a V-letter shape on the plain view, and a spacer 14a, made of synthetic resin or aluminum, is embedded in a space formed by the inner side of the yoke 13a and the permanent magnets 11a and 12a.
These parts are housed inside a housing 15a formed of aluminum or a non-permeable material,and only the inner surface on which the permanent magnet 11a, the spacer 14a and the permanent magnet 12a are connected with each other is exposed; thus, a magnetism applying circuit unit 10a is formed.
A threaded hole 22a, securing the opening engaging plate 20 which will be described later, is formed in one side face of the housing 15a, and two threaded holes 31a, for securing the sliding engaging plate 30, are also formed in the other side face.
Moreover, in the other magnetism applying circuit unit 10b two threaded holes 21b, for securing the opening engaging plate 20, are formed in one side face of the housing 15a and a threaded hole 32b, for attaching the sliding engaging plate 30, is also formed in the other side face
