Kazibuthe abahlukile eMhlabeni.

Lo mkhuba uzibuthe is esintwini eyaziwa isikhathi eside. It lethiwa sibonga emzini magnetite, okuyinto ayese-Asia Minor. Kwaba kukhona ukuthi isamba esikhulu nsimbi kwatholakala. Ukukhuluma zokuqala izakhiwo esiyingqayizivele kukazibuthe singathola imisebenzi Tita Lukretsiya Carus, owabhala ngayo e inkondlo yakhe "On the Umhlobo vesche" emhlabeni BC mina ekhulwini

Kusukela ezikhathini zasendulo, abantu baye bathola ukuthi ukusetshenziswa izakhiwo eziyingqayizivele nsimbi. Omunye amadivayisi ezivamile, umphumela eyayisekelwe ukukhangana metal, steel ikhampasi. Manje kunzima kakhulu ukuba Cabanga ezihlukahlukene izimboni, okuyinto babengeke nje bagcine ngokuthola zisebenzisa odonsa futhi electromagnets.

Amandla kazibuthe Zomhlaba - iyona ndawo emhlabeni, esivikela ke kusukela imiphumela eyingozi enemisebe emisebeni yelanga. On okuvela kulo mkhakha ososayensi phikisana kuze kube yilolu suku. Kodwa iningi labo wayekholelwa ukuthi kwaphakama ngenxa core eMhlabeni. Maphakathi iplanethi yethu ine uketshezi yangaphandle futhi kwangaphakathi ingxenye okuqinile. Ngokushintshanisa ingxenye liquid ikhenela idluliswa izinhlayiya kagesi begqoke ukuhambisa bese bakha okuthiwa kazibuthe.

ensimini eMhlabeni magnetic nayo okuthiwa i-magnetosphere. Umqondo "uzibuthe" - bemvelo oluphelele futhi global komhiaba. Okwamanje, akunakwenzeka ukwakha ithiyori ngokugcwele ephelele ilanga namandla adonsela phansi umhlaba, kodwa manje isayensi ukuzama ukuqonda futhi ngezindlela eziningi uphatha ukunikeza incazelo eyanele obukholisayo izici ezihlukahlukene zaleli mkhuba eziyinkimbinkimbi.

Eminyakeni yamuva, ososayensi izigebengu nezakhamuzi nje kungenxa ngiwukhathalela udaba lokho Amandla kazibuthe omhlaba kancane kancane buthakathaka nguwo. Ngokwesayensi liye kungase kutholakale ukuthi amandla kazibuthe iye kancane kancane buthaka past 170 iminyaka. It kwenza uzibuze, ngoba uhlobo oluthile isihlangu evikela umhlaba nezilwane kusukela ezimbi emisebeni elangeni. Magnetosphere Umhlaba umelana ukugeleza izinhlayiya yokuthi fly ngase-pole. Zonke lezi notshwala agcinwayo kule ungqimba engenhla umkhathi-pole, ukwakha into enhle - the Aurora Borealis.

Uma ensimini eMhlabeni magnetic ngokuzumayo zinyamalale noma kakhulu inciphe, ukuthi zonke izinto emhlabeni kuyoba ngaphansi kwethonya oqondile emisebeni cosmic nelanga. Ngebanga lalokho, lokhu kuyophumela izifo ngemisebe izilonda sazo zonke izinto eziphilayo. Umphumela yale nhlekelele kuyoba kuguquka esibi noma ukubhujiswa okuphelele. Kwathi gidi, kwanda akunakwenzeka.

Ososayensi paleomagnetology sikwazi ukunikeza ubufakazi okunokwethenjelwa ngokwanele ukuthi kazibuthe njalo umsindo oshintshashintshayo, inkathi la oscillations lihlukile. nabo uqobo babe cishe ejikeni oscillations ensimini futhi wathola ukuthi okwamanje emkhakheni usesimweni eyehlayo, futhi ngeke yehle ambalwa iminyaka eyinkulungwane. Khona-ke uyobe futhi kube kukhulu iminyaka eyizinkulungwane 4. I last Inani esiphezulu ekhangayo kazibuthe wafika ekuqaleni kwenkathi yamanje. Izizathu zalokhu ukuntengantenga ukubeka phambili ezihlukahlukene, kodwa ezinye theory ethize kulokhu ayikho.

Sekuyisikhathi eside kwaziwa ukuthi emikhakheni eminingi kazibuthe abe nomthelela omubi eziphilayo. Ngokwesibonelo, ucwaningo senziwa izilwane luye lwabonisa ukuthi amandla kazibuthe angaphandle mukela ukuthuthukiswa, kancane ukukhula kwamangqamuzana futhi ngisho ukushintsha ukwakheka kwegazi. Yingakho iziphepho magnetic ziholela ukunganakekelwa kwempilo meteodependent abantu.

Ukuze ensimini ukuphepha komuntu eMhlabeni magnetic - ngedawo nge value of ukungezwani ezithile ezingadluli 700 Oe. Kuyaphawuleka ukuthi lena akuyona mayelana emkhakheni langempela eMhlabeni magnetic, futhi amasimu kagesi, okuyinto yilabo abake ngesikhathi nokuqhutshwa umsakazo noma idivayisi kagesi.

Uhlangothi ezingokomzimba nqubo ithonya Amandla kazibuthe omhlaba phezu komuntu lingacaci yize kunjalo ngokuphelele. Kodwa sathola ukuthi lusebenza ku izitshalo: ukuhluma futhi okunye ukwanda imbewu kuyinto encike ngqo okusekuqaleni ukuma isihlobo sabo kazibuthe. Futhi ungakwazi ukushintsha noma ukusheshisa noma ukubambezela ukuthuthukiswa zalesi sihlahla. Kungenzeka ukuthi ngolunye usuku leli impahla izosetshenziswa kwezolimo.

Amandla kazibuthe Zomhlaba - kungamandla okudonsa. Kwezinye izindawo ke kuyehluka, kodwa ngesilinganiso kuyinto 0.5 oersted. Kwezinye izindawo (okubizwa ngokuthi anomalies kazibuthe) ukungezwani ukukhuphuka 2E.
