The tube 40 is mounted in the housing 20, the permanent magnet 50 and the electromagnet 60 are both disposed on the side of the tube 40, and the permanent magnet 50 is disposed between the electromagnet 60 and the tube 40. In the present embodiment, the electromagnetic water treatment apparatus 10 has a pair of permanent magnets 50 and a pair of electromagnets 60 respectively disposed on opposite sides of the tubular object 40. The permanent magnets 50 and electromagnets 60 arranged in pairs may enhance magnetic field stability and magnetic field strength.

The magnetic induction of the electromagnetic field generated by the electromagnet 60 and the permanent magnet 50 is preferably in the range of 2000Gs to 3000 Gs. The magnetic induction intensity is controlled within the range of 2000 Gs-3000 Gs, the generation of scale can be accelerated (see the research on scale prevention and scale prevention of water magnetization treatment), so that the scale is generated in the device in advance and is attached to the tube wall of the tubular object 40 of the device, and the aim of purifying water quality is fulfilled.
