The south pole seems to be a bit stronger to control algae and odor elements as well as ionizing minerals that would otherwise build up in water systems. A soft water effect is realized by magnetic water treatment. Less soap, better rinse, smoother hair, is obtained by magnetically treated water. It also makes it easier to wipe up the dried ions after a car wash. Plants and animals, as well as humans, benefit from magnetically treated water.
Single polarities are more effective than mixed polarities.
For example, using both south and north poles together tends to give a more south pole effect, magnetically and take longer for healing actions. Please come back soon and visit me. I will be adding material to this page as quickly as I can.
