Magnets n absolute zero

Just a first gues off the top o fmy head, but I think the presence of a magnetic field intruding on the filings would constitute an input of energy, raising the temperature so that they atre no longer at 0^oK. But if you could get the filings to 0^oK and keep them there while in the presence of a magnet, they should remain unneffected. For any change to take place requires energy, and there is no energy at absolute zero.

 

Interesting.
I wonder if this experiment has been done while using liguid nitrogen, for example, and comparing the results at normal temperatures.

 

It's a nonsense question. You can't reach absolute zero.

The question cannot be answered by existing theory -- it is a singularity. Anything could happen. You could suddenly find yourself upside down, wearing your grandma's underwear. There's no way one can even speculate what will happen in a physically impossible situation.

You have that dream too huh? disturbing, ain't it?!

I think the only "hypothetical" thing we can say about absolute zero is that nothing moves. The magnetic field coming into proximity of the filing would constitute a change in their environment, therefore an input of energy.

 

chroot, take it easy. Man, i think if this forum was real life you'd be a serial killer. i mean, sure, it is impossible...but dont get so upset.

Lets simplify and just ask how the attraction of a magnet to cold iron compares to the attraction of a magnet to warmer iron.

Besides - what's the big deal with the 'entire unpredictability of an impossible situation'? If absolute zero is similarly impossible, couldn't you similarly say that crazy things could happen such as "wearing your grandmothers underwear'?

 

Indeed, one would think so. After all, magnetic interaction on a target material is dependent, in large part, on the movement ability of the electrons within that target materials' atomic structure. So, without specific examples, I believe you are correct in concept.
I could see how a super-cooled ferrous material would have definite and different properties of potential magnetic attraction or reactivity to an outside magnetic field. Conceptually, it should be less.
Curious if any actual experiments have been done to establish effect parameters.

 

Just curious, how is magnetic attraction measured?

 

you WOULD be doing this in a vacuum, um, right? I hope so, because if you reaced a steady and constant tempature of absolute zero, wouldn't the air around it freeze and keep freezing all the air everywhere on the surface on the earth? Do all chemical changes/reactions stop at absolute zero?
