More tricks using an 11-Tesla superconducting electromagnet. These are used for chemistry research; for determining the detailed shape of unknown molecules using "two dimensional nuclear magnetic resonance."Y'know, I've heard that if you place a tray of water under one of these magnets, the water will curve into a bowl shape, exposing the bottom of the tray. The Red Sea is parted. But nobody wants to try it. Too much expensive electronics might get wet. [LATER] Tried it. Didn't work. But perhaps the gradient was too small. I'll try it on another magnet.Also see http://amasci.com/unew.html

no it won't. i think iron in our blood is dissolved in liquid, and its presence in the body is minimal... in xmen3 however, iron in that guards body was somewhat 100%(v/v), in whatever the solution is...

I think you can be used in a tank and stop the bullets

eww.

I've always wondered if that was even possible, although since I've worked close to a 700MHz machine and it didn't do much. Although prolonged working with them puts you at risk of heart murmurs as the fields interferre with the nodes in your heart there's generally not a risk with them (though I keep getting an image in my head of someone's piercing flying across the room).

aeroscope....I am more concerned with the Iron PLATE in his HEAD!

Saying superconductivity only occurs at somewhat higher temperatures is pretty misleading. I understand what you meant, but you make it sound as if room temperature is below 77k (−196 °C/−321 °F) (which would make my room pretty damn cold)

"NYEH!" LMAO.

If the magnet is that strong...isn't it dangerous coz it will suck out the iron in your blood like in Xmen 3

how good is that for your health to be in range of such a high magnetic field?Like would the iron in your blood be effected for starters?And would it magnetize things within range?My grandfather told me of magnetic field mine detectors vehicles in WWII, with all the people who were in them on a daily basis eventually dying of blood cancers.Then there is the Curies and their work with Radium and their resultant cancers.I don't mean to rain on your parade, I love this stuff, but be careful.
For those considering buying a new vehicle, don't forget to check out the new 2008 Toyota FJ Cruiser. Great for adventures off road, just for cruising around town, or running to the store.

The new 2008 Toyota FJ Cruiser seats five and comes in two-tone with a Voodoo Blue, Titanium Metallic, Black Diamond, Sun Fusion, Sandstorm or Brick body color and White top. The interior fabric color is Dark Charcoal, while the dash, center instrument panel trim and the door inserts match the body.
