Water is non-magnetic. How can magnets affect it?
The magnets affect the minerals in the water–the cause of scaling and corosion–and thereby the magnets change the feel of the water to make it feel and act like soft water. After passing through a magnetic field, water’s minerals no longer cling to the inside of pipes or to other surfaces they come into contact with. Scientific evidence (Expert Views) shows that magnetic water conditioning is, when properly installed, successful in the control of scale and corrosion.
