Saltwater Desalination With Magnet and Aluminum Idea

I believe it is silly that the world has not figured out a way to desalinate water in a way that is sustainable and relatively cheap compared to current methods which are cost prohibitive.

I was able to reduce the salinity of water by 0.6% with just a weak magnet and an aluminum tube. I had a theory that you can use a magnet to push aside the sodium and chloride ions (dissolved salt) within an aluminum tube by lowering a magnet into the tube and siphoning off the water that is above the magnet.

In future experiments I will get a stronger magnet and thicker aluminum tube to test again and see if a stronger magnet yields better results. Will also try with copper instead of aluminum.

In practice, I believe that you could repeat this process of desalination over and over until you get fully desalinated water or close to that. Possibly an array you could make of tubes with magnets that would lower in sync such that the water becomes less saline as it passes through each tube as it spills over into the next.

For the test I used about 1/8th teaspoon of salt in about 1/4 cup of water. Used a digital salt meter to measure amount of salt in the water. Did not want to try higher salt concentrations because the meter is not able to read higher concentrations. This is about proof of concept.
