Over the last week or so, we installed an above ground pool. The local water truck can't bring enough water in one load to fill the pool. To make up the short fall, to make sure the pool bottom doesn't have any leaks, and to make sure the pool was really level, I put in about 18 inches of water from our well. The water was quite red. (We have a very complex system to remove the excessive iron from our well water.)
So, to my question . . .
I went down to my shop and got a very heavy duty dual-magnet I use to hold things in place when I'm welding. It is strong enough to pick up my small 50 lb. anvil.
I put it on a rope and lowered into the pool to see if it would attract any of the iron. Nothing! I then set it against the liner on the outside of the pool for a couple of hours to see if it would pull iron near it. Nothing.
So, why doesn't a magnet attract iron present in water?
