The properties of magnetized water undergo a series of physical and chemical changes, but they are not visible in appearance. However, it can still be identified indirectly. You can use a new kettle to boil water. After boiling it several times, if there is no scale in the kettle, it can be proved that the water is magnetized water, because magnetized water has no scale. If there is scale, it proves that the water is not magnetized water. I hope the poster will adopt it
