<P>PROBLEM TO BE SOLVED: To provide a magnetic body separation apparatus which can separate a magnetic body, such as oxygen, from a fluid, such as ozone-containing gas, with high efficiency and high tolerance with regard to ozone or the like, and can be operated for extended period. <P>SOLUTION: There is provided the magnetic body separation apparatus 1, wherein a fluid containing a magnetic body is circulated in a flow passage 41 made of air-permeable material having a magnetic field gradient to separate the magnetic body outside the flow passage 41 so as to concentrate molecules having smaller magnetic susceptibility compared with the magnetic body, and a plurality of projection parts 45 projected from an inner wall surface of the flow passage 41 to a cross-sectional direction to reduce a passage cross-sectional area are provided in predetermined spaces along with the flow passage 41. <P>COPYRIGHT: (C)2013,JPO&INPIT |
