World's Most Powerful Magnet Under Construction in Florida
Posted by Sean Fallon at 9:20 AM on September 3, 2008
You have probably heard stories about patient injuries or death occurring when someone introduces a heavy metal object into the same room as an MRI machine. Obviously, we are talking about some seriously powerful magnets here. However, the US$10 million magnet currently under construction at the National High Magnetic Field Laboratory in Florida is expected to reach 100 tesla when finished—about 67 times more powerful than a typical MRI machine.
That is just the kind of power needed to test the properties of high-temperature superconductors like iron oxyarsenide which may result in better, cheaper MRI machines and high-voltage power lines. It could also be used for certain zero-gravity experiments and magnetic propulsion systems that could eliminate the need for traditional rockets down the line. Researchers have been able to create magnetic fields over 100 T for years, but if successful, this would be the first magnet that could repeatedly hold up to the strain. According to Greg Boebinger, director of the Magnet Lab, the magnet will have to resist Lorentz forces "equivalent to the explosive force of 200 sticks of dynamite packed into a volume of space the size of a marble."

This combined with the Large Hadron Collider will surely destroy the earth. Pity, I was curious who would win the US presidential election.

Uh, actually... no. I never heard of this. Great, thanks Gizmodo... one more thing to add to my Woody Allen-esk phobia list.

The original article in IEEE Spectrum Online should be read, as it is full of interesting tidbits:
"Lorentz forces-the electromagnetic push on electrons that attempts to force them in a direction perpendicular to the flow of current."
"Enough energy is transferred during those 2 seconds to raise the magnet's temperature from the cryogenic cold of liquid nitrogen to nearly 200 °C. It takes an hour to cool the magnet enough to start another round of pulses."
"Several ingredients in the secret sauce will let this magnet snap back where others have simply snapped. The magnet is made up of nine nested coils of wire. At the heart of the two innermost coils, where Lorentz forces create pressures 30 times as great as those at the bottom of the ocean, researchers have placed state-of-the-art nanoparticle wire composed of 82 percent copper and threaded through with silver strands no more than a few hundred atoms across. The copper-silver combination is stronger than either metal alone by a factor of 100."

@nystreetfilms: Seriously, you've never seen Jet Li disarm the bad guy by turning on the MRI machine in "The One?" (OK, so the bad guy was Jet Li too, but you get the image).
Right then. When the NHMFL pulls the LHC through the Earth's crust, creating a massive tunnel between Geneva and Tallahassee, causing a catastrophic collapse of major portions of the sea floor while creating a black hole deep inside the planet, we'll see who's laughing then.

Can it be used to deflect the fiery debris from an unmanned NASA launch as it explodes mere seconds after liftoff? 'Cause there are probably a couple dozen people who might have liked to have one of these installed near their favorite parking spaces back in 1997.

But the question I have: Is it REALLY the most powerful ever made? You really think it's stronger than the Z-Machine Magnet Los Alamos played with decades ago? I kind of doubt it, but I don't know or can't say exact numbers.

@DNA it is not in Orlando. It is in Tallahassee (which is the capitol of FL. Just some FYI for everyone who thinks Orlando or Miami is the capitol). I can already see it now, Bobby Bowden will be using this thing for one of his trick plays.

Yep, wiped my credit cards working on a big mag. Only once! I learned my lesson. ;-) The thing also magnetized my Swiss army knife which actually made it kinda handy for picking up tiny screws.
I wonder though, is this new magnet as powerful as "The Magnificent Magical Magnet of Santa Mesa"? That thing would drag cars around.

So, if we survive the black hole created by that Particle collider launching in 8 days (forgot the name), we can attack this magnet to it, and suck all the iron and cobalt in the universe to our planet!

Heh, My family are great friends with Greg Boebinger. My dad is the lab fellow at NHMFL New Mexico and, when Greg was there, he worked with my dad a lot. They actually shared offices. I in the building adjacent to NHMFL NM at LANL, but I go i'm in there all the time asking my dad and his colleagues questions. Interesting work.
Anyway, I just thought it was really cool to see this. I've been to NHMFL Florida a few times, but my dad is out there all the time working on projects with them.

@theblackdog:
Mythbusters disproved the rumor that powerful magnets (specifically MRIs) can react with any iron-based pigments in tattoos (probably the worst to have, iron-oxide, is illegal for use as a tattoo pigment anyways). Besides, if a tattoo could cause problems, so would other sources of iron. Such as the hemoglobin in your red blood cells. Stand next to a sufficiently powerful magnet, and it should be able to rupture all of your red blood cells even as you're drawn towards it. Then again, a magnet that powerful is likely to crush you with all those cars that suddenly come flying towards it.

Also, how awesome is this? Someday we will build a magnet big enough to interrupt earth's natural magnetic poles, causing a devastating tilt in the earths axis resulting in an extreme planetwide ice age that will last for thousands of years! it wont be this magnet, but someday...

No, but it _is_ diamagnetic, meaning it will be repulsed by any applied magnetic field. Diamagnetism is generally too weak to really notice, but with a magnet that strong...perhaps it will be strong enough to notice.
