Abstract: A water magnetizing mechanism provided in a cylinder comprising an upper mounting assembly including an inlet and a first channel; a lower mounting assembly including an outlet and a second channel; tubes each, interconnected the first and second channels; and a magnetic assembly including magnetic rings put on the tubes, each magnetic ring having two opposite magnetic poles such that a magnetic field having a direction from one magnetic pole to the other magnetic pole is generated, non-magnetic members each sandwiched between the magnetic rings, and magnetic field absorbing plates each disposed longitudinally between the tubes for absorbing the magnetic field. Water flowing from the inlet is adapted to flow through the first channel, the tubes, and the second channel repeatedly until all of the tubes are traversed so as to be magnetized prior to exiting through the outlet.
