Digital Compass - yindlalifa ikhampasi magnetic

Kukho iimpikiswano kwimbali, ngokucacileyo baya ukuba nayiphi na impendulo ephosakeleyo kunjalo, kuba zisekelwe iphutha elibi. Omnye Wesuka kutshanje kuphela, ekubeni uluntu ezikhuphile inkqubo ye yokumisa equka: omnye abe ngqo - inqila yedijithali okanye magnetic? Abantu ukubuza lo mbuzo, ngokucacileyo into engenziwayo izifundo geography esikolweni ...

Lo iinkcukacha wokuqala umbuzo: kuhlobo pole ufuna ukuya?

Impendulo ibonakala sobala. Bubonakala nakakhulu ignoramuses kunye neendibano geography, xa ifowuni ukuba ziya ekuqhelaniseni ikhampasi Hadrian wakhonza emhlabeni (ngoku into inqabile, ngendlela), perforce wafunda ukuba isiphelo oluhlaza inaliti yekhampasi isoloko ibonisa ngasentla. Ngenxa yoko, xa kwipali esentla. Ngako oko, isiphelo red - emzantsi.

Ngoko kusengqiqweni, kodwa asiyonyani. Loo mpendulo ibiya kuba efanelekileyo, umzekelo, ngenkulungwane XVIII, xa sphericity komhlaba sele wabonakala, kodwa ke phezu kwentloko yakhe kunye "antipode 'icala none of the abaphandi abazange khangela. Noko ke, imbali ikhampasi ngokubanzi akukho izibonda wazazi ebutsheni bakhe. ekuqaleni nje nge Chinese amandulo, sabona ukuba inaliti zentsimbi magnetized usoloko ukhomba indlela enye, kwanokonwabela navigation kumhlaba kwaye elwandle. Xa ikhampasi kwinkulungwane XIII ethunyelwayo ngokusebenzisa Arabhu waya eYurophu, abathetheli iinqanawa ekuqaleni Lumkela ukusebenzisa i ezintsha - besoyika yokuba betyholwa ngobugqwirha. Kodwa xa ndicinge ukuba kwenzeka ntoni, ndaqalisa zpoha Great ezifunyaniswe eendawo, nto leyo ikhampasi weqiniso engena uludwe izinto inkulu ingqondo yomntu.

Ngenkulungwane XIX, kunye kweminyaka 10 British wamazwe polar Dzhon Ross kunye nomtshana wakhe uYakobi sifikelelwayo, ngokulandelelana, ngasentla nangasezantsi nezibonda kazibuthe Umhlaba. Kwaye thina kwaoko sizimisele ukuba ngaba ungqamane izibonda zejografi.

Kamva kwenzeka oko akwanelanga - nkqu kwexesha kumphezulu komhlaba. Bona ukuba khampasi yedijithali, ngemagnethi akukho ubusela. avareji isantya intshukumo - ngeekhilomitha ezili-10 ngonyaka. Malunga emithathu enesiqingatha iinkulungwane, kwipali esentla otsalayo ebhadula nje emdeni eKhanada, kwaye kwisiqingatha sesibini senkulungwane lokugqibela, ngequbuliso kunye izinga "eyoyikekayo '(ngo-2009 - 64 km ngonyaka ngamnye) wazikrazula eRashiya, ukuya Taimyr Peninsula. Ngoko ke ikhampasi nosiba, ukuba ulandela ngqo kuya kukusa kwi-Arctic ice pack, ukusa kwinqanaba kunye zilungelelanise 85 ° 54 'imizuzu inkululeko emntla 147 degrees nezide ngasempumalanga.

Ngoku ukuba bayiqonde, baya kuqonda ukuba indlela ikhampasi lwedijithali, oko elektroniki. Akukho umazibuthe apha, Kakade, ingafuneki. Umamkeli lwemiqondiso kwiisathelayithi GPS okanye GLONASS imisela indawo yayo, kubeka i data kwi kwigridi nokulungelelanisa imaphu kwaye kwangoko ibonisa indawo wekhusi ukuya emantla, kodwa lo mzekelo - ophezu Yomhlaba.

Yonke eminye imisebenzi yefowni elektroniki ugqitywa injongo yayo. I lungisa eziphambili kakhulu uncedo ukukhumbula iindlela kweshumi namakhulukhulu iibhakana, ukulinganisa umgama nesantya, ubale amanyathelo athathwe, kwaye kunye calories ukuba batshiswa ngexesha elifanayo. Xa ndithetha inyani, akukho nokuba ikhampasi, kunye navigation.

Kwaye ngoko okwesibini kubalulekile ukucacisa umbuzo wokuba inqila yedijithali onayo engqondweni. Ekubeni kukho izixhobo ezisebenzisa kwisifundo soLwazi ezimbini-axis resistors ngemagnethi. Enyanisweni, ukuba - nekhampasi enye Classic, iqinisekisa ulwalathiso izibonda ezo Imagnethi yomhlaba. Ngawo onke imiphumo.

Kodwa, abathandi athandekayo izinto ze-elektroniki, i wenza ntoni, ukuba yonke oomatshini inkunkuma okanye ashiywe ngaphandle amandla? Ayiloncedo kule ityala ikhampasi wakho olungileyo endala magnetic?
