Masta - that was my thought, too.
The principles that these devices cite are real. Electrophorysis can be used to purify water by drawing ions to charged plates. The problem with these devices is that they are nowhere near strong enough and do not have enough contact time. Say you pour the wine at a rate of 5 oz. in 5 seconds. That's 1800 cc/min, or roughly 1/2 gpm. The device appears to be 1.5" long, and the ID of a standard 750 ml bottle is 3/4". If you pour with the neck half full, the contact time with the magnetic field is 180 milliseconds.
Just how much effect will a magnetic field not strong enough to damage your watch, applied for less than a fifth of a second, have? Not bloody much, as the Brits say. Perhaps if the wine were pumped through an electromagnet running on 20A of 440V power (like a MRI machine) there might be some effect.
However, considering that getting an MRI is considered less dangerous than an X-ray, and the magnetic flux in an MRI is millions of times more powerful than that device, I don' think it is doing any more than the Fuel Magnetizer did on my truck.
As far as the "experts" who agree, as cited on their website, WHO, WHAT, WHEN, WHERE? These devices always seem to have testimonials from people who cannot be located. Back in the day, the water treatment devices cited research institutes in the Soviet Union whose existence could not be confirmed.
Sorry for the rant. The first account I ever lost in the water treatment biz, when I first started out as a salesman, was to one of these things. Perhaps I'm just biased.
