Do magnets on pipes affect water hardness
« on: 18/10/2010 13:15:55 »
There is quite a thriving industry suppling magnets to be fitted to water pipes which reputably act as water softeners.
At first sight this would not seem to work as it would seem to require strengths of say 10T to have much effect on water while I doubt whether these magnets exceed .1T.
Surprisingly sales are brisk and people swear by them, is it just a placebo effect or do they do something real
We need the services of our resident real chemist.

This was one of the questions of the week a while back:  http://www.thenakedscientists.com/forum/index.php?topic=22492.0

To sum up that thread, they almost certainly don't work on lime scale buildup, but they might help remove iron oxide and other magnetic materials.

Geezer Enterprises (Extremely Limited), Inc. recently acquired off the back of a truck a large supply of super-duper water softening magnets and we are pleased to offer them to ewe for a very reasonable 10 quid a pop.

This remarkable device, invented by the famous physicist P. T. Barnum, will also cure acne, water on the knee and extreme flatulence.
