To uniformize magnetic irradiation, to shorten the distance between permanent magnets, to effectively radiate high strength magnetism, to increase the flow velocity of a fluid by its collision with each groove and a collisional merger between the fluid currents, to enhance magnetization efficiency, and to perform mixing/dispersing of fluids by the complex shearing force during the collisional merger.
A magnetic fluid processing structure 2 consists of a layered structure body 7. A first plate 5 is provided with an outside through hole 8, and a second plate 6 is provided with an inside through hole 9. The inside through hole 9 and the outer periphery through hole 8 are communicated through a communicating flow path 10. The communicating flow path 10 is constituted of a plurality of annular grooves 11 and 11a and a plurality of communicating grooves 12 and 12a, and permanent magnets 15 and 15a are fixed so that they face across the communicating flow path 10. The entire structure is held in a casing 3.
