Abstract
Disclosed herein is a magnetic treated suitable for arrangement in a flow path of a fluid so as to introduce the fluid into a magnetic field to perform its magnetic treatment. The magnetic treater includes a magnetically-acting member having at least two magnetically-acting surfaces magnetized in opposite polarities and maintained opposite to each other at a predetermined interval via an interval-limiting means, a fluid inlet, a fluid outlet, and a casing. The casing is provided with the fluid inlet and fluid outlet and encloses the magnetically-acting member in such a way that at least spacing between the magnetically-acting surfaces is in communication with the fluid inlet and fluid outlet and serves as a flow passage for the fluid. As the magnetically-acting member, stacked permanent magnets or a combination of a permanent magnet and magnetic pole plates connected to and magnetized by the permanent magnet may be chosen.
