 The effect of magnetic field distribution on the micro processing for inner wall of a horizontal positioning pipe was investigated. The processing tool installed ring-shaped permanent magnets between spacers utilizing magnetic compound fluid (MCF) was inserted and rotated in the pipe. In the experiment, the characteristics of material removal, velocity distribution of magnetic clusters and pressure distribution on the inner wall were investigated using the tool with different structure. Relation between these characteristics and the magnetic field distribution was clarified. In the case of using the tool which can hold much MCF, the material removal follows as Preston's law, and thick and long magnetic clusters deform on the perimeter of the permanent magnet.
