Milgauss & Hybrid Cars Info
*** SAW THIS ON ANOTHER FORUM & THOUGHT I'D SHARE ***
** Hope I'm not breaking any forum rules. If so, Mods please delete ** "Just noticed this article in the NY Times re electromagnetic fields inside hybrid cars. "E.M.F. levels of up to 135 milligauss at the hip and up to 100 milligauss at the upper torso" quoted on field strengths. From Wikipedia: "The earth's magnetic field is 0.5 gauss, a small iron magnet is about 100 gauss, a small Neodymium-iron-boron (NIB) magnet is about 2,000 gauss, a big electromagnet is about 15,000 gauss." The measurements in the hybrid are clearly much lower than these levels. An interesting topic nevertheless. Toyota says there's no problem. http://www.nytimes.com/2008/04/27/automobiles/27EMF.html"

Toyota would say that.

Great, I bought a Prius for work and thought it was the greatest car ever. Just my luck!

Those levels quoted are far too little to be of any concern. The Gauss rating on the watch is 1000 Gauss. That is a fairly high magnetic resistence. Magnetic force also dissipates tremendously over very small distances.
For example, a powerful MRI magnet produces 15,000 Gauss (or 1.5 Tesla) at the bore (the opening) or 15 times the rating of the Milgauss watch. The strength of that same 15,000 Gause MRI dissapates down to the 1000 Gauss level around 5 feet away from the opening of the MRI machine. I wouldn't try it personally with an $8,000 Milgauss but your watch should be safe from damage as long as you keep it several feet away from an MRI bore. An MRI would most likely be the strongest magnetic field most people would ever have a chance of encountering in their everyday lives. Far more powerful than the magnetic force of any Hybrid car or for that matter, far more powerful still than a large electromagnet hanging from a crane in a scrap metal yard that picks up cars and iron beams weighing thousands of pounds. BTW, you'd have to be inside the MRI room with your watch on to test this theory which the technologists running the scanner wouldn't allow you to go in there since ferrous metals are not allowed near the magnet. The "miligauss" term they are using is in one/thousandth of a gauss. So, 135 miligauss would equal .135 gauss. THe Milgauss Rolex is resistant to nearly 10,000 times the magnetic force generated by the Hybrid. I wouldn't worry about the car hurting your watch, in other words |

Now I can go back to thinking this is the greatest car ever made. BTW, if there are any "Tech Geeks" out there, you should check these cars out. Alot of technology. For $1,200 I had the interior of the Prius customized to replicate my Caddie. I drive this car more then the Caddie.

Thanks for sharing! Imho, there is so much hysteria about the influence of magnetism on mechanical watches. Your post shows clearly that sometimes you have to take a deep breath and don't be so afraid of your watch getting magnetised.
