The direction of the magnetic field of the magnetizing part is perpendicular to the direction of water flow, so that a good magnetizing effect can be formed on initial water flowing through the magnetizing part.

It can be understood that the magnetizing part is formed by the way that the initial water of the permanent magnet passes through the middle of the magnetizing part and is magnetized into magnetized water.

It will be appreciated that the electromagnetic coil, when energized, produces a magnetic field that magnetizes the initial water. It should be noted that, the first sub-pipe section wound by the electromagnetic induction coil is made of a non-metallic material, which not only can be penetrated by a magnetic field, but also is not easily magnetized. The non-metallic materials that can be selected are polyvinyl chloride, polypropylene, polytetrafluoroethylene, etc.
