This amazed me. I wanted to share. I am lacking scientific knowledge to discuss this topic though.

What you are looking at is a Type II superconductor exhibiting the phenomenon known as flux pinning. 
One of the cool things about superconductors is that they expel magnetic fields from their interior (aka the Meissner effect). This is what causes the very weak and unstable levitation of magnets from Type I superconductors (the magnet can easily fall off of the superconductor or vice versa), because the superconductor is simply pushing against all magnetic field lines in its effort to expel them from it's interior.
Type II superconductors also exhibit this effect, but form small tubelike quantum vortices in its structure, that allow magnetic field lines to pierce through the superconductor through these small tubes of non-superconducting material (aka flux tubes). These tubes form as an energetically favorable condition when a strong magnetic field is forced into place around the superconductor (such as when the superconducting disc in the video is forced towards the magnets by a person). Once the tubes form, they are usually able to hold their shape under the force of gravity produced by the superconductor, and thus the superconductor is pinned in space by the magnetic field.
When magnetic field lines are forced in place around the superconductor, these flux tubes configure themselves to closely mirror the field lines attempting to pierce the superconductor. This is why a track of magnets aligned along their poles like this:
[(N-S)(N-S)(N-S)....(N-S)]
will generate field lines that are roughly parallel with the track surface, allowing the superconductor to ride around the track, guided by the field lines and flux tubes much like a roller coaster is guided by its rollers and its track.
Let me know if any of this didn't make sense, I tend to ramble...

One of the more interesting things I experienced was a copper bracelet given to me by my father; it had copper oxide nanowires growing on it. This bracelet demonstrate some weird shit; it absorbed gold plating after being dipped into baking soda water and touched to a gold plated nut, you could see the gold slowly crawl across the crystals; the scratches on it would fill in; if you set it on the curved part and started rocking it you could come back an hour later and it would still be rocking, and it varied in weight depending on it's ph and how the magnets were set in the holes; if hung on a string from a tree branch the whole thing would anodize into rainbow colors, but only if it wasn't grounded out.
Little did I know the copper oxide nanowires had superconducting properties and quantum effects;

Sorry, but even cupric oxide nanowires don't exhibit superconductivity at room temperature. 
Additionally, gold is pretty chemically inert, and would not easily migrate to a tarnished copper bracelet, nor would baking soda water affect this outcome.
Just sayin

1. Tell me what happens when you stick a bar of gold to a bar of iron and submerge in saltwater. 2. Idk about the superconducting properties, but arrays of the wires display some interesting quantum effects (google it) 3. The fucking bracelet became magnetic... it's COPPER. 4. The metal that the bracelet ate (both the gold, and eventually the stanless steel coating off of the magnet) migrated across the surface of the green tarnish (the nanowires, probably some sulfur in there too). 4. When I used some metal detarnisher/polisher on the green (that treated wool stuff) it turned into a shiny, white metal. And then the nanowires would regrow, all on their own, turning it back to the irredescent green. The metal that the bracelet "ate" would basically migrate on the surface of the copper, filling in scratches, and then hang around the magnets (clearly showing some of the magnetic field of the magnet from the opposite side of the copper).
Also, I tested pencil led on it, the graphite would not come off, it had bonded to the green stuff. After dipping the bracelet in baking soda water. (if I dipped it in vinegar it would quickly become shiny and not exhibit the wierd metal eating behavior. One magnet ate the copper making the hole bigger which it eventually fell out, the other magnet got ate by the copper, and got all rusted and shit, and is now stuck in the hole.

Ok, we’ll play this game: 
Quote:
1. Tell me what happens when you stick a bar of gold to a bar of iron and submerge in saltwater.
A galvanic potential is set up, and the iron acts as the SACRIFICIAL ANODE and is the one that corrodes. The gold will be protected from corrosion due to CATHODIC PROTECTION. Nothing will happen to the gold, but the iron will rust at a rather fast pace, and potentially cloud up the saltwater with corrosion products. I fail to see how this supports any point you’ve made thus far.
If your “gold nut” was brass however, then the zinc in the brass would be the anode in the reaction, and may have plated out on the surface of the copper bracelet. If the Zinc layer is sufficiently thin (as I would expect it to be using such a weak alkaline solution and small timeframe), then it could appear as a gold layer.

I’m well versed on the subject, and the quantum effects demonstrated at room temperature have nothing to do with the macroscopic phenomena you are describing. Would you care pointing out what specific property you are implying is happening?

3. The fucking bracelet became magnetic... it's COPPER.
You had not mentioned this in your last post. You seem to describe this thing as having magnets set into the bracelet, which may explain why the bracelet appears to be magnetic. Why don’t you describe how you verified that the bracelet was magnetic, while also eliminating the possibility of the bracelet’s magnets from throwing off the result.
You say you can see the nanowire “crystals”, when in fact this is impossible without a microscope. Additionally, there is no evidence that cupric oxide nanowires spontaneously grow in bulk at room temperature. Even if this were happening, there would not be the perfect array of equally spaced nanowires at equal lengths necessary for quantum effects to be observed on the macroscopic scale.
You realize that copper has been around for a long time, and it’s chemistry has been thoroughly studied (as have the nanowires formed from its various oxides), and yet there is no information anywhere describing what you claim has occurred. I believe you are witnessing a unique tarnishing pattern across a normal copper bracelet, possibly influenced by the presence of a magnetic field and the magnet’s materials themselves (also getting caught up in the galvanic corrosion). Unless you can present to me a series of detailed tests and observations that show that:
1. You know enough about the subjects involved to understand what you are seeing and know how to control sources of experimental error. 2. You have set up controlled, repeatable experiments to eliminate sources of error and have come to your conclusion based on logic that is ready to be peer reviewed.
Then you can not jump to such wild conclusions such as the ones you have just posted. Room temperature, near perfect arrays of nanowires from a common bracelet….room temperature macroscopic quantum effects and superconductivity….room temperature, bulk migration of gold onto copper by just dipping in baking soda solution…these are some heavy, heavy claims to make. Then you expect to come into a Science and Technology Forum and make these claims with such weak support, and get all bent out of shape when someone calls you out?
You sir need to chill, and work on getting more evidence.

Ok, I will attempt to do a series of experiements on it. The other thing that I noticed was how hard the copper was getting, the bracelet eventually snapped in half (probably normal for copper). Anyways, a correction, it is rosegold, meaning a mix of gold/copper.
And yes, I did a bunch of experiments on this bracelet, including heating it after cleaning to grow some nanowires. I don't have a microscope, but will attempt to identify wether or not what I am seeing is just copper sulfide crystals growing parellel to the surface.
I will start with a basic observation of the bracelet, including pictures. I will then clean up the bracelet with vinegar/evershine if I can find it. Then I will demonstrate it's magneticism (half of the bracelet lacks a magnet). After that, I will hang the bracelet and show off it's self galvinizing properties (the green stuff should grow back). I will then attempt to demonstrate any metal eating properties of this strange thing. ANything I missed will be included.

Sweet, I can't wait to pour over the results. 
I will keep an eye on this thread, if you decide to post your own thread, please me about it.
