PROBLEM TO BE SOLVED: To treat contaminated fluid by a ferromagnetic field and to facilitate the maintenance of a magnetic treatment apparatus together. SOLUTION: A casing forming the main body of the magnetic treatment apparatus is partitioned and a pretreatment chamber in an inverted trapezoidal column shape communicating with the inflow port of fluid along the flow and an aftertreatment chamber in a trapezoidal column shape communicating with a discharge port are provided respectively. Permanent magnets are internally provided to both left and right sides of the casing, and a pair of sealed magnetic force chambers in the trapezoidal column shape and a rectangular magnetic treatment chamber communicating with the pretreatment and aftertreatment chambers is provided to the center part of the casing. In the magnetic treatment chamber, an intermediate magnetic pole body constituted of a plurality of punching steel plates and a plurality of magnetic pole rods is clamped and a device with a check valve for sending out air to the pretreatment chamber is attached. A rectangular opening is cut and formed at the center part of the top plate of the casing, the opening is closed with a cover and the casing is sealed. The intermediate magnetic pole body is attachable and detachable to/from the opening of the casing by detaching the cover together with an air send-in device to which the cover is attached.
