    In the circuitous haze of my mind
    I was watching this video and wanted to know more about it.

    My idea behind it is that all mass innately wants to allow its magnetic momentum to flow, and that the liquid nitrogen like it does to elements like mercury, eliminates the resistance that is naturally occurring in the atoms, and in this case instead of allowing electricity to flow more freely, it allows the materials field to do what it wants.

    But what really interests me is that it must not have a normal magnetic field like seen in the diagrams of regular magnetic fields. A normal magnetic field would cause a magnet on top to flit over so that it can touch the base magnet...since it doesn't naturally want to be repelled (negative on negative wants to become negative on positive). In this video it is apparent that neither repulsion nor attraction may be going on, yet the above object must be a magnet to take this effect; so how does the magnets field react with the superconductors? As you can see, he pushes the magnet around and adjusts in at different angles, meaning that there is no real epicenter of the magnetic flux. Or could it be that, superconductivity just raises the item to a higher energy state? If that were so, it could be explained as the bottom of the object being cooled, therefore gaining potential, then as a way to release the potential, like in a light emitting diode, it equalizes the potential by releasing it in a form of energy; for an LED electricity to light, in this case, cold potential to a form a of magnetic flux that just dissipates outward. And, by the object such as YBCO releasing its field, it is completely submerging the magnet in a universally reactive field so that regardless of where the magnet is on a 3d plane, it is submerged in a near equal amount on force from all angles which supports it no matter where you reasonably place it. If this is correct, the magnetic field would look like a fire, with a high density at the beginning, and dissipating outwards into a weaker force as it rises. -But what if it doesn't rise, and instead goes in every direction from the source, since unlike heat, it doesn't have a reason to rise, unless you consider possible interactions with the planets gravity.

    Is anything I said remotely true? If not, can somebody explain it to me?

    Why superconductor cant heat up? I cant imagine how zero resistance is possible.

    In normal way electrons flow throw wire by jumping from one orbital to another, those jumps is reason of electromagnetic radiation (heat), am I right?

    So how electrons act in super-conductive material?
