Superconducting Quantum Locking is cool as ****

You learn the mathematics of how this works in 2nd year Engineering.

But what sucks is, it only works in super cold temperatures, like -200. So yea.. ****

why is it that at cold temperatures magnets are stronger?

User avatar #55 to #35 - Leopard (12/17/2013) [-]
It's all about the electrical resistivity of the metal that's floating, which decreases as the temperature is lowered. Less resistance allows for it to float better.

is it possible to make a superconductor at room temperature?

I'm currently working on a way to make that possible.

definitly possible, pretty much nothing is impossible, we just dont know how to do it yet

Man his fingers must be really cold then
User avatar #111 to #9 - dreaddune ONLINE (12/17/2013) [-]
-200 Celsius? i'm guessing it's only the one at the bottom that has to be that temperature, or his fingers would be frozen instantly..

But you wrote down in the comments as a reply that "It's all about the electrical resistivity of the metal that's floating, which decreases as the temperature is lowered. Less resistance allows for it to float better".

I'm getting confused here..
#161 to #111 - Rascal (12/17/2013) [-]
Superconductors float by having perfect diagmagnetism - which means that the magnetic field is "mirrored" suspending the magnet or the superconductor (depends which part is resting on the ground) in air. At a certain point of temperature, a material's resistivity drops to an unmeasureable value - this is called superconductivity and only when the material goes superconductive it will display perfect diagmagnetism (it floats when its under a certain threshold temperatur).

Besides his fingers would not freeze instantly - remember that energy (heat energy from his fingers to the superconductor) doesn't transfer instantly.

I should make an account.
User avatar #187 to #111 - Leopard (12/18/2013) [-]
The thing that's floating needs to be super cold too.
#241 to #187 - Rascal (12/18/2013) [-]
I'm pretty sure that only the superconductor (black material) has to be super cold for it to bend the magnetic field.

User avatar #186 to #117 - Leopard (12/18/2013) [-]
I've poured liquid nitrogen on my bare hands before.
#150 to #9 - Rascal (12/17/2013) [-]
However todays superconductors work at much higher temperatures, take for an instance the ceramic HgBa2Ca2Cu3O8, it becomes superconductive at 134 K, -138,15 C

What is cool about this is, that at these temperatures you can use liquid nitrogen instead of liquid helium (nitrogen = cheap and easy to produce, helium = expensive and not so easy to produce).

The most interesting part about superconductors is the use of them in MRI-scanners allowing great breakthroughs in the medical industry.

Leopard, your understanding of material, metaphysical and psychological aspects of science allow you to do things that could seem like magic to others. Therefore, you may as well be a wizard, due to your potential ability to manipulate the world around you in "magical" ways.

Your status as a year one student simply means you should come back and read this comment when you graduate.

That's not a railgun. A railgun uses electricity and to magnetic rails to accelerate the projectile.
#134 to #123 - iwilldeletenotatw (12/17/2013) [-]
He said homemade, so I think he probably meant "not the real thing." Like you make a homemade telescope with an empty paper towel roll. At least that's the way I read it.

Correction: I thought it said homemade because i've seen the gif before. now I feel like a jackass. I still think that's probably what he meant.

I just recently uploaded this which is a demo form my uni course, it shows a different magnetic effect which has nothing to do with super conductors but is equally cool, check it out guys!

The stuff looks like liquid nitrogen. So my guess without googling.

Under very low temperature magnetic field somehow flips and poles reorient themselves. But I might be completely wrong.

Maybe the iron realigns itself just on the top layers since the the dude pushes the magnet down?
User avatar #141 to #102 - alucardhell (12/17/2013) [-]
It is a magnet over a super conductor. The super conductor has been cooled down (using liquid nitrogen) in order to allow it to actually show superconducting qualities which only happens around 77K or lower. Basically the magnet causes a current loop to be formed in the superconductor which causes a magnetic field to be produced by the superconductor which repels the magnet. Basically as long as the superconductor is kept cold enough, the magnet will perpetually float that far above it. The reason that this usn't being used for say floating cars/cites is that we can't produce superconductors that work above ~80K (-315.67 F).
