Forgive me for being slow; We have always been told to keep magnets away from electronics, especially computers. Some places in the world have these Maglev trains, and it would seem to me that the magnetic force required to levitate 200 tons would destroy any electronics you would bring aboard, would it be safe to bring a laptop on a maglev train? If assumed safe to have a computer on a maglev train. What about a bed. I just read this article about a bed levitated on magnets; http://dvice.com/archives/2012/05/maglev-bed-lets.php Obviously it required less force to levitate a 200 pound bed than a 200 ton train, but in the bed you would also be closer to the magnets, how close could you be to a magnet before you would damage i.e. computer. Could you lie in bed with your laptop?
