Ikhampasi isetyenziselwa ukuqhelaniswa nesifundo. Umgaqo-nkqubo wayo usekwe ekusebenzisaneni nentsimi yehlabathi, kuba ikhampasi ngokwayo ikwanguMagnet. Itolo yakhe inokujikeleza ngokukhululekileyo. Kodwa ifowuni iya kuziphatha njani kwizibonda zemagnethi?
Yintoni isibonda semagneti yomhlaba kwaye siphi?
Iplanethi yethu inendawo yemagnetic (i-geolognetic), yenzeka malunga ne-4.2 yezigidigidi kwiminyaka eyadlulayo. Ngokweenguqulelo ezixhaphakileyo zezazinzulu, zenziwa ngemithombo yangaphakathi (ekore). Le ntsimi isebenza ngokuhamba iindleko zombane, kunye nemizimba enomzuzu wamagnethi, ngaphandle kwemeko yombutho wabo.
Imagnethi ye-magneti yenza owona msebenzi ubalulekileyo. Ikhusela umhlaba, iisatellite zesathephetha kwiziphumo zamasuntswana e-cosmic, umzekelo, umoya welayini. Phantsi kwempembelelo yentsimi ye-gegragnetic, indlela yokuhamba kwabo iyatshintsha.
I-Magnetic Pole yindawo enemiqathango kumphezulu womhlaba, apho imigca yentsimi ikwi-angles elungileyo. Izibonda zemagneti zimbini, kunye nendawo kunye nendawo nasezantsi, kodwa azihambelani.
Ngapha koko, ngokwemithetho ye-magnetism yomzimba, i-South Pole ibekwe emantla, emantla emazantsi. Kodwa, ukuze kuthintelwe ukudideka, izazinzulu zavuma ukubabiza ngendlela eqhelekileyo.
Inyaniso enomdla: I-Manetic Pole yaseMantla yafunyanwa nge-1 kaJuni, 1831 ngendoda yesiNgesi uJ Ngo-1841, wagqiba kwelapho i-South Pole (i-Antarctica) ifumaneka khona.
Izibonda zobungangamthetho azingowe-antipode, kuba intsimi yomhlaba ngu-Asymmetric. Bakwintshukumo engapheliyo, kwaye intshukumo yezibonda ilungiswe ngononophelo ziingcali. Umzekelo, i-North Pole ihamba ecaleni kwe-elliptical trajectory kwaye ngokuthe ngcembe itshintshela emantla.
Malunga neminyaka engama-400 wayekwindawo yeArctic eCanada. Ngokutsho kwezinto zokuqala zezazinzulu, sele ziku-2020 pole zazifanele ukuba ziseRussia. Nangona kunjalo, isantya sentshukumo yakhe sitshintshile. I-South Pole ngelo xesha kumda weAntarctica.
Injani ikhampasi?
Kuxhomekeka kwimodeli yesixhobo, inokuxhotyiswa ngemithi enye okanye ezimbini. I-Complow Row Roll ibonisa i-North (okanye emantla nasezantsi, kule meko indawo yaseMantla ihlala iphawulwa ngombala othile). Utolo lwemagneti lubekwe ecaleni kwendawo yentsimi ye-geomagnetic.
Ukufumanisa indlela, ikhampasi ine-the the the the the. Utolo lususwe kwi-refuiner (kufuneka ukuba lula). Ngokomthetho we-magnetic pos, izibonda ezifanayo ziyaphoswa, kwaye zaza zatsalwa. Ke ngoko, ikhampasi ihlala ibonisa indlela enye.
Ikhampasi ibonisa isibonda semagneti yomhlaba, kwaye ayisiyondawo. Kuba abangqinelani ngokwenene, kwaye izibonda zihlala zihamba, impazamo ethile ivunyelwe, kodwa ayibalulekanga ukuba iqhelene.
Inyaniso enomdla: Ngo-2019 (okokuqala ngqa ngeminyaka engama-360), i-manytic kunye nendawo yendawo ye-magnetic kunye nendawo yendawo. Oku kwenzeke kwi-zero Greenwich Meridian eLondon.
Ngaba umsebenzi wekhampasi uhlala emantla nasemazantsi ePhepha?
Kwingxowa yemagneti, ikhampasi isebenza ngokungachanekanga. Esi sixhobo senzelwe ukusebenzisa ngokuthe tye - kwesi sikhundla, utolo lubekwe kwimigca yamandla kwaye ibonisa indlela. Kwizibonda zemagneti, imigca yamandla ibekwe kwi-angle ye-90º. Ukuba i-hull krolo ayiyi kulungiswa ngokukhuselekileyo, iya kufuna ukuthatha indawo efanayo ethe nkqo.
Ukufundwa kweentolo kule meko kuya kuxhomekeka kwiimpawu zoyilo lwekhampasi. Ukuba ilele ngokukhululekileyo kwi-axis, iyajika kwaye iyeke ukuhamba. Ukuba utolo luyabetha kulwelo, luya kuthatha isikhundla esingabalulekanga.
Ubungqina bekhampasi kwizibonda zemagnethi azichanekanga, kuba iimeko zokusetyenziswa kwayo ziyaphulwa. Ngokwesiqhelo utolo lubekwe ngokuthe tye - ecaleni kwemigca yamandla yentsimi yeGeogragic. Kwizibonda, imigca yamandla ibeka esime nkqo, ke utolo lumthanda, kodwa oku akubonelelwa nguyilo lweCompass.
