Oxygen Is Magnetic?

peter_d_sherman 5y ago
Apparently liquid oxygen IS in fact, magnetic! But -- also observe that the liquid oxygen is not "pancaking" on one of the magnetic poles! Instead, it's acting as sort of a "bridge" -- between the poles! Compare this effect with the effect of creating a high-voltage "bridge" -- between two adjacent beakers of water at room temperature: https://www.youtube.com/watch?v=6ZzuFGw4XCg https://www.youtube.com/watch?v=6ZzuFGw4XCg Now, the $64,000 Question: Are these two effects related? ? Oh sure, one of them deals with an elemental fluid which is supercooled in a magnetic field, and one of them deals with a compound fluid at room temperature in an electric field -- but aside from those relatively minor (but actually somewhat major!) differences (and adjusted for scale, frequency, temperature, etc.) -- is the underlying phenomena (the underlying Physics!) -- the same? Why or why not? ? Well, I for one, as of the point in time of this writing, do not know! <g> But... As I said ("as I alluded to earlier!" <g>)... That's the $64,000 Question! <g>

This video shows a close up: https://www.youtube.com/watch?v=KcGEev8qulA https://www.youtube.com/watch?v=KcGEev8qulA In particular look at http://www.youtube.com/watch?v=KcGEev8qulA&t=1m55s http://www.youtube.com/watch?v=KcGEev8qulA&t=1m55s > Are these two effects related? I guess no. In the first experiment, the effect is just the attraction of a paramagnetic material to a high magnetic field area. The idea is that the Oxygen does not modify the magnetic field too mush, but it is attracted to the part where the magnetic field is strong. This video looks interesting https://www.youtube.com/watch?v=u36QpPvEh2c https://www.youtube.com/watch?v=u36QpPvEh2c The bridge is not important, you should be able to add a few drops and they will stick to the magnets, and add more drops and they will stay in the middle until the bridge is form. In the second experiment is more like a surface tension effect, where the high electric potential increase the surface tension. Also, the water is dielectric, so it will change the shape of the electric potential and make it higher in the bridge. So you can't add drops to each side because the electric potential and the surface tension are not high enough. In the experiment they put the cups together so the usual surface tension is enough to create the bridge because they are very close, and once the bridge is formed they separate slowly the cups.
