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.
