For this reason, the ring-shaped magnet 110 can be easily attached to the conduit 1. Further, after the arc-shaped magnets 111 and 112 are attached to the conduit 1, the arc-shaped magnets 111 and 112 can be connected by the coupling member 114 to form the ring-shaped magnet 110.

  In each of the above-described embodiments, it is desirable that the magnetic processing apparatuses 10, 30, 50, 70, 90 disposed in the conduit 1 include a cover member that covers the ring magnet. As the cover member, a synthetic resin heat shrinkable sheet can be used. The entire magnetic processing apparatus constituted by arranging a ring member on the conduit 1 is covered with a heat shrink sheet and heated. Thereby, a magnetic processing apparatus can be covered with a cover member. The cover member can securely hold the ring-shaped magnet in the conduit and can prevent the ring-shaped magnet from being damaged. In addition to the heat-shrinkable sheet, a synthetic resin cylindrical member that covers the ring magnet can be used as the cover member.

  In each of the above embodiments, an example in which a ferrite magnet or a neodymium magnet is used as a magnet has been shown, but the type of magnet is not limited. The number of ring magnets can be changed as appropriate.

  Since the magnetic processing apparatus according to the present invention can remove impurities in the fluid with high efficiency, it has industrial applicability.
