Ukwahlukana Magnetic: undoqo kunye nesicelo ngokoqobo

Ingxaki yokuqhelaniswa nezifundo sithuba lusoloko umi phambi umntu ahlekise kakhulu. Ngokuqhelekileyo, akukho sithetha imigama ezincinane, xa ungakwazi ukuthatha phezu umthi umlimandlela odinokostoyaschee okanye ilitye elikhulu thina. Sithetha indawo enkulu apho umhambi iba ikhampasi oyintloko nabagadi babaviwa abancedisayo. Kulo mzekelo, akakwazi ukwenza ngaphandle iimpawu lwezakhono njengoko azimuth kunye declination ngemagnethi.

Esikolweni, siyazi ukuba azimuth le angle ezikhandelwa phakathi ulwalathiso yomntu okhethiweyo kunye ndaba kwicala langasentla, inaliti yekhampasi uyawalathisa. Noko ke, yonke loo nto kukuba inaliti yekhampasi a alathe i North Pole, njengoko kukholelwa ngalo, kwaye indawo North magnethi mandla ayanelanga ukuba wahlukile ukusuka kumhlaba, kodwa utshintsho ekuhambeni kwexesha (Noko ke, ezi nguqu zenzeke kancane kangangokuba zingakotshwa ngoyaba).

Ngoko, kwenzeka ukuba abantu ezichaphazela ikhampasi owahluke ngokwemvelo, akuyonyaniso. Ukuba uhambo inkampu elula, ngoko eli impazamo nazo zingananzwa, kodwa ke iinqanawa elwandle, moya esibhakabhakeni kunye nezinye izixhobo kufuneka bakhokelwe ncam ukuba azimuth oyinyaniso, intlekele kungenzeka ngenye indlela.

azimuth Liyinyaniso elokuba, ngolu hlobo lulandelayo kwisicatshulwa ngasentla, i-engile ephakathi kwicala le into okanye nayiphi na enye indawo yesalathiso ulwalathiso ngokwezelizwe North Pole. Umahluko phakathi azimuth Imagnethi yomhlaba kunye oyinyaniso uye wabizwa declination ngemagnethi. Sele iyinto eyaziwayo ukuba ukuba declination magnetic na indlela ukuya ngasempuma, ibizwa ngokuba "Mpuma". Ekhethwe iitafile ezizodwa uphawu "+". Ukuba phezu koko, lo declination magnetic yi "West" kwaye zibonakaliswe ngolu phawu "-".

Ingcamango declination magnetic iye yaziswa ejikeleza ngonzululwazi sokuba ixesha elide: Umlawuli odumileyo Columbus H. kusetyenziselwa kuphela xa uhambo lwakhe edumileyo kunxweme of America, kodwa uza kuba ngowokuqala ukutsala ingqalelo into yokuba ixabiso layo kuyahlukana nedlela intsimi elinikiweyo.

Ngoku akukho mathandabuzo ukuba ixabiso ngamanani declination magnethi eyahlukileyo kwiindawo ezahlukeneyo zomhlaba. Umzekelo, eMoscow na-80, lo gama ezinye imimandla ifikelela amanqanaba ezibalulekileyo. Oku kubaluleke ngokukhethekileyo ukuze bakuthathele ingqalelo declination magnetic xa usebenza iimaphu, xa ufuna ukwenza ukuguqulela rhoqo kwi azimuth lokwenyaniso Imagnethi yomhlaba kunye vice versa.

Gunners ukulungisa ukudubula yakho usebenzisa isixhobo ezikhethekileyo - nekhampasi. Xa kufikwa ukumisela indlela ngqo ukuya kwindawo reference, nto leyo ke isetyenziswe njengendawo yokuqala xa endizixunayo. Xa umongo wayo, ngoncedo inaliti yekhampasi iguqulelwa ibe azimuth lokwenyaniso ngemagnethi.

Ngoko ke, lo declination magnetic - yemali elibizwa magnetic olwahlukileyo kwesele oyinyaniso. Olu lwazi kuyimfuneko nje kuphela xa besenza amaphulo ixesha elide, kodwa ebudeni badubula zokudubula, kwakunye ngenxa yokuhla eqhelekileyo iinqanawa-moya.
