Supplementary answer:
1. Electromagnetic//permanent magnet will do. But only a good magnetizer can penetrate the iron pipe (the most difficult) and induce the fluid to form "magnetized water". Not just any magnet, of course.
2. "Magnetized water" is water with "energy". Will gradually lose. After about 10 days, it will return to normal water.
3. Boiling magnetized water will not affect it.
4. Magnetized water is "living water" with "energy". In about 2 months, the hard scale in the inner container of the water dispenser can be completely softened. Drop it at the touch. Isn't it amazing? "Living water" can enhance human immunity ... It is amazing that other manufacturers talk about "magnetized water". I don't comment.
5. A good set of 200g "magnetizers" can magnetize all 10 tons of water in two hours.
