At first I thought that this is mysterious and inexplicable. Then it occurred to me that since water molecules are electric dipoles, they would be subject to the Lenz effect when in a magnetic field, i.e., they would resist a change in orientation. Since the normal random thermal motion of the molecules would be more or less restricted, depending on the strength of the magnetic field, the rise in temperature of the water to ambient would be suppressed. This might also explain the precipitate. The normal Brownian motion caused by thermal agitation would also be suppressed, resulting in the water's inability to keep small paricles in suspension. The water would have to have some fine particulate impurity in the first place for this to happen. And here's some speculation: Suppose you place a beaker full of water inside a larger container with a non-polar liquid. Expose these to a strong magnetic field. Would the water become colder and the non-polar liquid hotter? Anti-entropic? Naaah. Howdy Michael, We were able to drop out some white powder precipitate one a single occasion some time back.We had forgotten to turn off the test unit over the lunch hour. Never able to reproduce the event in our steel test tank. The municipal source of our water supply could have had been hypo-chlorinated that day... or some chemical agent to reduce manganese.. or visa-verse. Using a plexiglas tank with aluminum frame and municipal chlorinated water would occasionally produce the precipitate and severely oxidize the aluminum. You idea of using a non-polar liquid is intriguing. Glad we have been giving the next test rig modular design theme some time for input like your speculation. If you would like to see a pic of the present setup I can send you a pdf. Richard
