Pokaz efektu Meissnera przy użyciu wysokotemperaturowego ceramicznego nadprzewodnika i magnesu neodymowego
Lühikirjeldus
[muuda]KirjeldusYBCO video.webm |
English: A superconductor or a high-temperature superconducting ceramics is an alloy of oxides of yttrium, barium and copper in proportions (which you see on the screen) YBa2Cu3O7-x and abbreviated as YBCO. In order to demonstrate the properties of this object let’s conduct an experiment. First, let’s take a small piece of ceramic and then put a piece of styrofoam and a powerful neodymium magnet on top of it. Next, the superconductor is cooled with liquid nitrogen down to -196 degrees Celsius. After the ceramic is cooled, take a piece of styrofoam out from underneath of the magnet. The effect of levitation is caused by the ceramics cooling down to the critical temperature, it then becomes a superconductor, as well as a perfect diamagnetic.
This means that it can repel any magnetic field, as well as create its own when being near a strong magnetic field. The phenomenon is called the Meissner effect. If the magnet is lifted the conductor next to it begins to lift with it as well. The magnet and the superconductor are almost like "frozen" together in space.Français : Démonstration de l'Effet Meissner avec un aimant en néodyme en lévitation magnétique au-dessus d'un supraconducteur à haute température critique.
