World’s strongest magnet

[lilhasselhoffer]

I don't even know how to describe how awesome this is. A magnet of this scale has real potential in the materials science field. It assuredly has other, more niche, uses; the really valuable part is research.

As far as some of the other comments, I have to question the logic. I apologize for anything offensive in advance, but from what I am reading these people miss the future potential because they cannot look past the immediate needs that they perceive.

This crap pisses me off. How about spending 2.5m towards something useful like an electric vehicle infrastructure that could be of benefit NOW rather then "hopes" that "one day" "some thing" may lead to the development of "some other thing"? Their making crap just to make crap. Bet he drives a nice car with those government grants. At least he can afford the gas.

You confuse research, with throwing money at what you believe is reasonable. While I understand the altruistic desire to remove gasoline from the power grid, 2.5 million dollars wouldn't even be enough for a small city. The research that these people do could possibly lead to new battery making techniques, which will make your new electric car actually feasible.

Bemoaning spending 2.5 million on actually viable research hardware, when we spend that much daily on stupid farming subsidies (spend 5 minutes to look it up; in order to maintain prices the government pays farmers to let land lay fallow).

Shit, they could have just given that 2.5m to charity and stuff or other sensible/practical stuff. Whats the use for this magnet anyway? Just for show? Next weapon of mass destruction?

Altruism is a nice goal, but you really draw the line in the sand at an odd place there. By your logic owning a computer while there are starving people is a sin, your income beyond the bare minimums of survival should be donated to charity.

While abrasive, my statement is true. If you look back in history the greatest inventions were brought about by research and capital investment; the inventions then increased the standard of living by providing both easier lives and a steady source of employment (look at the television, automobile, and airplane). These things could never have been developed without research. Those people without vision see a 2.5 million dollar waste, those with vision see 2.5 million dollars that will yield billions in end user products.

Perhaps a less myopic view is a necessity? Even blunting the potential possibility with reality, you must recognize that this research will pay for itself. Perhaps the next time you get an MRI (NMRI to those unafraid of proper terms) you will concede the value of extremely powerful magnets.

Haven't you read Dan Brown's Angels and Demons ?

The magnet won't have a practical use in it self, it'll mostly be used in studies and researches that will hopefully yield results that can benefit humanity in any ways. More efficient electric motors ? maybe even vehicles that move by altering earth gravity on them !

Guess not.

Lets hops it pays off.

Humans aren't magnetic, are they?

No we are not magnetic. You must mean "attracted to magnet" and the answer is still no but somebody correct me if i'm wrong.

Perhaps reading the other comments might lead to a little bit more insight:

They could levitate frogs and grasshoppers in that thing.

Diamagnetic levitation can be used to levitate very light pieces of pyrolytic graphite or bismuth above a moderately strong permanent magnet. As water is predominantly diamagnetic, this technique has been used to levitate water droplets and even live animals, such as a grasshopper, frog and a mouse. However, the magnetic fields required for this are very high, typically in the range of 16 teslas, and therefore create significant problems if ferromagnetic materials are nearby.

http://en.wikipedia.org/wiki/Magnetic_levitation

Human beings are mostly water. While there is hemoglobin in the blood, we are mostly a diamagnetic polar molecule (H2O). This means that we could, given a supremely powerful magnet, be levitated.

Iron in the human body is generally bonded with oxygen in a hemoglobin molecule. This means it plays little role in magnetic interactions. To put this in perspective, MRIs would not work if we had copious amounts of unbonded iron in our blood. The comment about Magneto sucking iron out of you, through strong magnetic fields, would be a painfully appropriate analogy.

That's the "why bother" attitude holding us back. This is one project. Billions are spent on funding private "research projects". Do they have a goal in mind? Which is why I said "hopes" that "one day" "some thing" may lead to the development of "some other thing". We're spending WAY too much money on hopes and dreams then we are on solving real problems.

I should ask them for a few million in grant money so I can build the worlds largest fan in hopes that one day it will blow away humanities problems.

DON'T YOU SEE THE IMMENSE IMPORTANCE OF FURTHER MAGNETIC RESEARCH IN REGARDS TO YOUR BRILLIANT IDEA FOR THE ENORMOUS FAN THAT MAY(and I'd say "WILL") ONCE AND FOR ALL BLOW AWAY ALL OUR ETERNAL CONFLICTION???

...Think about it. Support the grants.

I think from your perspective 2.5M is not a really big deal but for me, being in a different state of mind because I am in a very poor country, that amount could do something big. I hope you understand me because I understand what you want to point out.

That is why in my previous post I said "somebody correct me if i'm wrong". I may not be as intelligent as you and others that is why I accept to be corrected.

Anyways, thanks for the info.

I can visualize that fan as I type this... It will be the Scythe Gentle Typhoon AP-310000 and it will be equipped with 12 stators and each stator will have one of these magnets... It will spin at 300'000'000 rpm and will barely be able to cool the next iteration of Fermi cards.

Do you really want to go down that road ?

 

[xXSebaSXx]

Would it make have made you feel better if I had said "it will barely be able to cool the HD6990"?

PS: Is fanboy-ism that strong around these parts that a simple joke at nVidia's expense gets feathers ruffled?

 

[Shihab]

YESNo. why would I feel better ? I wasn't feeling mad or anything to begin with.

PS: Is fanboy-ism that strong around these parts that a simple joke at nVidia's expense gets feathers ruffled?

Nah, not much fanboism here (not much witnessed since I joined at least). People care first about performance around here. Don't get the wrong idea about this place because of an idiot like me .

what.. u dont want a super useless magnet?

Now the world has a new record. 100.75 T. Magnet scientists are feeling really happy!

Researchers at Los Alamos National Laboratory's biggest magnet facility have just met the grand challenge of producing magnetic fields in excess of 100 tesla while conducting six different experiments. The hundred-tesla level is roughly equivalent to 2 million times Earth's magnetic field.

The team used the 100-tesla pulsed, multi-shot magnet, a combination of seven coils sets weighing nearly 18,000 pounds and powered by a massive 1,200-megajoule motor generator. There are higher magnetic fields produced elsewhere, but the magnets that create such fields blow themselves to bits in the process. The system at Los Alamos is instead designed to work nondestructively, in the intense 100-tesla realm, on a regular basis.

Congrats and well done. It can lead to other discoveries.

In recent experiments, said Mielke, "the new magnet has allowed our users and staff to pin down the upper critical field of a new form of superconductor, discover two new magnetically ordered states in a material that has eluded scientists for nearly 30 years, observe magneto-quantum oscillations in a high temperature superconductor to unprecedented resolution, determine a topological state of a new material, and discover a new form of magnetic ordering in an advanced magnetic material."

This technology has a good potential for science

I am having a *woosh* moment here; how is this dangerous to people? Humans aren't magnetic, are they?

Not a lot, but the human body does have iron in it, like the hemoglobin in your blood which your body needs to move oxygen throughout your body. So it is kind of important. Iron is also one of the most abundant elements in the universe.

We are made up of star stuff afterall. So no surprise that the most abundant elements in the universe make us up.

 

[de.das.dude]

Your mistaking magnetism for gravity.

with metal shoes silly.

 

[lilhasselhoffer]

Iron is also one of the most abundant elements in the universe.

Just missed being in the top 5. Iron is number 6, and is approximately one quarter as plentiful as Carbon (number 5).


In a less nit-picky fashion, 100 T is nuts. At that strong of a magnetic field every single atom is influenced by that magnetic force. I'm waiting for them to announce that these kinds of fields will make cold fusion a reality. I can dream, no?

I think that would be gravity, not a magnetic field.

This magnet would probably be helpful in destroying bra clasps...

 

[Aquinus]

http://solomon.as.utexas.edu/~duncan/magnetar.html

The strongest magnetic field that you are ever likely to encounter personally is about 10^4 Gauss if you have Magnetic Resonance Imaging (MRI) scan for medical diagnosis. Such fields pose no threat to your health, hardly affecting the atoms in your body. Fields in excess of 10^9 Gauss, however, would be instantly lethal. Such fields strongly distort atoms, compressing atomic electron clouds into cigar shapes, with the long axis aligned with the field, thus rendering the chemistry of life impossible. A magnetar within 1000 kilometers would thus kill you via pure static magnetism --

more like rip the clasps through the bewbs-lungs-etc if the person is facing the magnet.

Scientists build another crazy magnet:

http://www.symmetrymagazine.org/article/physicists-build-ultra-powerful-accelerator-magnet

This 1.5-meter-long model, which is a fully functioning accelerator magnet, was developed by scientists and engineers at Fermilab, Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, and CERN. The magnet recently underwent an intense testing program at Fermilab, which it passed in March with flying colors. It will now undergo a rigorous series of endurance and stress tests to simulate the arduous conditions inside a particle accelerator.


The magnets currently inside the LHC are made from niobium titanium, a superconductor that can operate inside a magnetic field of up to 10 teslas before losing its superconducting properties. This new magnet is made from niobium-three tin (Nb3Sn), a superconductor capable of carrying current through a magnetic field of up to 20 teslas.

Oldie but goodie thread. Subbed

Question... how many T's is typically produced by an MRI?
