Effekti na Meissner da Amfani a Effekti na Meissner

Idan Superconductors, suka dace kadan da suke shiga wurin hanyar, suka fito magnetic field da ba suka gano a cikinsu. Wannan alama a cikin superconductors suna ne Meissner effect. An samu wannan alama a shekarar 1933 ta wanda 'yan lissafin jamiyar Alaman “Walther Meissner” da “Robert Ochsenfeld”. A lokacin wasu, suka ce binciken magnetic field a arewa cikin sampulun Tin da Lead masu superconductor. Su suka nuna cewa idan sampulu ya sake tsarki kadan da suke shiga wurin hanyar a kan magnetic field na gaba, yadda magnetic field a arewa sampulu ya zama. Zan iya cewa wannan ziyarta a arewa sampulu na nufin cewa magnetic field ya fito daga babban sampulu. Wannan alama ya nuna cewa a cikin hali na superconductor, sampulu ya fito magnetic field na gaba.

Meissner State

Hali na superconductor na tana da suna Meissner state. Misalai Meissner effect ana bayyana a cikin tasirir.

Meissner state ya jawe idan magnetic field (ko external ko produced by current flowing superconductor itself) ya zama da ma'ana mai yawa, kuma sampulu ya faru a yi aiki a hukuma masu conductor na gaba.

Application of Meissner Effect

Wannan alama na superconductivity, an amfani da shi a magnetic levitation wanda shi ne yanayi na high-speed bullet trains. A hali na superconductor, saboda fitowa magnetic field na gaba, sampulu na superconductor material ya mika a cikin magnetic field ko vice-versa. High-speed bullet trains sun amfani da wannan alama a magnetic levitation.
