Lo mhlaba otsalayo of the current

Ukufunda iintlobo ngezenzeko magnetic lubonise ukuba apho kukho ombane, ie, iintlawulo sombane zezona kwisenzeko, kukho Imagnethi yomhlaba kunye yangoku.

Ngenxa yokuba lo mhlaba otsalayo senziwa malunga umqhubi xa yangoku aqukuqela kwi yamva, yona isoloko ijongwa njengomthombo lokusekwa lo mhlaba otsalayo. Ngale ndlela, ibizwa ngokuba 'lo mhlaba otsalayo ye yangoku. "

lwayo ngokuxhomekeka kwicala wamandla ombane kuyo kwenzeka endle.

Ubukho lo mhlaba otsalayo ngeenxa umqhubi kunye umsinga wombane ukubona eziliqela iindlela. Enye yezi ndlela kukusetyenziswa imvuthuluka yentsimbi. Kanye magnetic endle yangoku lamaqhosha zesinyithi, enamakhulu imvuthuluka zesinyithi, ngemagnethi babe iintolo ezincinane. Nganye kwezi neentolo lo mhlaba otsalayo olubekwe ukuze axis yayo ingqamana orientation lo mhlaba otsalayo kwindawo apho. Kunye nobuninzi iintolo ezinjalo ungabona indlela ukutshintsha indlela imikhosi senze lo mhlaba otsalayo, xa edlula ukusuka kwindawo enye ukuya kwenye intsimi. Oku kwintsimi kazibuthe imvuthuluka zentsimbi yangoku ekuthiwa omoya ngemagnethi.

Sisebenzisa imvuthuluka Imagnethi yomhlaba kunye cinga lo mhlaba otsalayo of current ngqo. Ngokuba lo umqhubi ukutsiba ngapha khangela uxwebhu yekhadibhodi, kunye paperboard ulitshize umaleko obhityileyo imvuthuluka yentsimbi. Siphawula ukuba bapase ezikhoyo chips umqhubi uya kuba ngeenxa zonke ngezangqa concentric.

Imigca kwi apho mhlaba otsalayo umgca neenaliti ngoku ezincinane owahluke ngokwemvelo, ekuthethwe imigca yakhe endle. Ngoncedo lwe migca amandla iluncedo kakhulu ukumela ngokwegrafu lo mhlaba otsalayo.

Umgca amandla ingqalelo ngendlela yokuba kodwa azikweli phezulu kulo naliphi na indawo ibonisa ulwalathiso amandla wayesenza kweli nqanaba ukuze i-North Pole.

Amatyathanga senziwa kumhlaba kazibuthe ngoku ngoncedo imvuthuluka zentsimbi zibonisa, yintoni na indlela yemigca amandla kwintsimi ngemagnethi.

imigca Amandla imagnethi - ivaliwe amagophe ngeenxa nombhexeshi. Ngokukodwa, imigca kazibuthe namandla ngoku phambili - ukuba izangqa concentric ogama amaziko abo kumgca yangoku.

Ukuze ubone yokuqhelwaniswa imigca mhlaba otsalayo ngenxa ulwalathiso ngoku, endaweni Sawdust kuyimfuneko ukusebenzisa inaliti ngemagnethi. Ezingqongileyo umqhubi yazo yangoku-Ukuthwala, njani ulwalathiso imigca yasendle. Xa yokuqhelaniswa iya kutshintsha i zangoku kwi kumqhubi iintolo malunga ngemagnethi rotated 180 °, nto leyo ibonisa utshintsho olungqamelanayo kwi kwicala imigca yasendle.

Ukuqhelaniswa imigca entsimini lo mhlaba otsalayo ezinxulumene kolwalathiso ngoku umqhubi yi umthetho olula, ecetywayo yi Scientist British Maxwell: ukuba ukuhamba phambili osengqiqweni iyafana kolwalathiso ngoku ngumqhubi, kwicala njengokujikeleza isiphatho nobhontsi xa ingqamana ulwalathiso imigca entsimini lo mhlaba otsalayo obukhoyo phakathi umqhubi.

Lo mthetho ngamanye amaxesha ibizwa ulawulo ekunene-ngesandla.

Ngoku thatha kruthu umqhubi kwisangqa, kwaye ngokugqithisela ezikhoyo kuyo, sibona indawo esisesweni kwi ikhadibhodi esekwe nkqo ukuya moya wesangqa kwakhona. Sifumana ukuba imigca Imagnethi anisezizo isangqa egqibeleleyo, kodwa kulo mzekelo, yonke imigca zivaliwe, ngokudlulisela umqhubi, apho kukho khona ngoku. Ngoko ke, lo imigca Imagnethi zisoloko ivaliwe ehlabathini yangoku.

Zabekwa kwiindawo ezahlukeneyo oku mhlaba otsalayo encinane, sikwazi ulwalathiso imigca yasendle.

ulawulo Ekunene-isandla sisebenza, Kakade ke, ukuba ngoku setyhula, kodwa kule meko iluncedo kakhulu ukutshintsha indlela yentsimi yangoku kunye zibuthe. Eneneni, ukuba ukubambelela nobhontsi ukutshintsha-lwangoku, ukuhanjiswa kwincam yayo iya kubonisa ukuba kubaluleke lo mhlaba otsalayo indawo yangoku setyhula.
