Magnetic water treatment

Magnetic water treatment (AMT) is the idea that passing hard water through a magnetic field will reduce scale without using chemicals. This idea isn’t supported by evidence. A 1996 Lawrence Livermore National Laboratory study found no significant reduction in scale. Because water with dissolved ions conducts electricity more, magnets only affect water a little, so magnetic water treatment is a hypothesis that failed testing and is now disproven. Any products claiming to use magnetic water treatment are fraudulent. Vendors often rely on photos and testimonials but provide little quantitative data or well-controlled studies, and they omit important details about system conditions and measurements of the water after treatment, such as hardness ion levels or the behavior of suspended particles.
