Apo patinotaura nezvazvo magnetic kuderera Panguva ipi neipi paPasi tiri kutaura nezve kona pakati penzvimbo yemagineti ekuchamhembe nenzvimbo yekuchamhembe. Iyo geographic kuchamhembe inozivikanwa zvakare nezita rekuti chokwadi kuchamhembe. Uku kudonha kwemagineti kunoratidza musiyano uripo pakati penharaunda yekuchamhembe neiyo inoratidzwa nekambasi, inova iyo yekumusoro yekumagineti.
Muchikamu chino isu tichaenda kukuudza zvese hunhu uye chii chinoshanda iyo magnetic kuderera ine.
Mhando huru
Magnetic kuderera haigare yakagadzikana papasi redu. Zvichienderana nezvatiri, kukosha kweizvi kunogona kusiyana. Zvakare, nekuda kwekutenderera uye kushandurika kufamba kwepasi uye nehunhu mhedzisiro, uku kukosha kweyekudzima kwemagineti kunochinjawo nekufamba kwenguva. Tinogona kutaura kuti izwi iri inotibatsira kurerutsa kusabvumirana kwese kuripo pakati pemamodeli ezvakanaka zvikonzero uye chokwadi. Inogona kutibatsira kuti tiwane pfungwa nezve kumahombekombe ekukanganisa uye zvikanganiso zvekuverenga zviripo mune zvinofungidzirwa zvine mwero zviyero masystem.
Izwi rekuti magnetic declination hariratidze kuti panogona kuve nemisiyano isingatarisirwe mumatanho ekubatanidza. Tinogona zvakare kuwana akasiyana maonero, geographies ayo akabviswa uye akagadzirwazve uye mimwe mikana yekugona kuongorora.
Kune boka rekutsvagisa uye rekugadzira iro rakavakwa munguva pfupi yapfuura uye iro rakagadzirwa nevanoona maartist, curators uye theorists vane basa ravo chikamu chekuziva kweakasiyana postcolonial uye decolonial zvidzidzo zvine padyo padyo mamiriro. Iri boka rekutsvagisa rinonzi magnetic kuderera.
Mashandiro anoita Magineti Kushambadzira
Kana isu tichida kuziva kuti ichi chinoshamisa chepasi redu chinoshanda sei, isu tinofanirwa kuziva izvo izvo magineti epasi. Planet Earth ine magnetic field nekuda kwekuumbwa kwepakati pePasi. Imwe yepasirese inonyorwa zvakanyanya nesimbi uye nickel. Idzi simbi dzinorema dziri mune semi-mvura mamiriro mukati mekunze kwepasi. Izvi zvinokonzerwa nekuwedzera kwetembiricha pakadzika uye kumanikidza kwakanyanya kunowanikwa idzi simbi dzakaumbwa nematombo.
Nekuda kwekufamba kuripo pakati pehutete hwezvinhu mukati mekati yepasi pane izvo zvinonzi convection mazaya. Aya maonerevhizheni emvura muhembe ndeaya anokonzeresa kufamba kwetectonic mahwendefa uye ayo anosimudzira kondinendi kutsauka. Uye zvakare, ivo ndivo honzeri yemagineti epasi.
Sezvo huwandu hwesimbi inorema iri mukuenderera kunoenderera, akasiyana magetsi magetsi anogadzirwa anogadzirwa panguva imwechete sekufamba uye nekugadzira iwo magetsi magetsi. Izvi zvinoita kuti Nyika iite seyakakura magineti uye iine maviri magineti matanda: kuchamhembe pole uye kumaodzanyemba pole. Kana tikataura kubva kumagineti ekuona, danda rekuchamhembe riri kumaodzanyemba uye riri padyo nenzvimbo yekumaodzanyemba pole. Pane rimwe divi, iyo magnetic kumaodzanyemba pole iri padyo nenzvimbo yekuchamhembe pole. Mamiriro ezvinhu eaya akasiyana magineti matanda epasi redu ndiwo anoruramisa danda rekuchamhembe remagineti kambasi tsono inonongedzera kunzvimbo yekuchamhembe. Iko kumira kwemagineti matanda hakunyatsoenderana neaya ematanda enzvimbo. Kana chiri chokwadi kuti vari padhuze navo kunyangwe vasingachengetedze chinzvimbo chakamisikidzwa. Ichi chinzvimbo chinosiyana pamakore akapihwa mafambiro akasiyana ePasi.
Geographic uye magnetic kuchamhembe
Iyo geographic kuchamhembe ndiyo inozivikanwa nezita rekuti chokwadi kuchamhembe. Inoenderana neekisheni yekutenderera kwepasi uye ndiyo inotsanangudza mukati: mharadzano ine pamusoro penyika. Kune rimwe divi tine geographic nzvimbo yekuchamhembe uye kune rimwe divi nzvimbo yekumaodzanyemba pole.
Kana tichitaura nemagineti tinogona kutaura kuti iyo magineti kuchamhembe pole inotsanangurwa neiyo magnetic field panonongedzerwa macompass. Iko kumira kweiyi magnetic kuchamhembe pole hakuenderane neiyo yenzvimbo yekuchamhembe uye yanga ichifamba kwemakore. Sezvo paine zvidzidzo nemishumo pane chinzvimbo cheiyi magnetic field, zvinozivikanwa kuti chinzvimbo chakasiyana makiromita zana nemazana zana kubva muzana ramakore rechi1100. Zvinonyanya kana kushomeka kuti gore rega rega iyo yekumagineti pole pole inoshandura nzvimbo yayo nemakiromita makumi matanhatu.
Parizvino iyo magnetic north pole iri pachinhambwe chemakiromita 1600 kubva kugeographic north pole. Inowanikwa kuchamhembe kwakadziva kumabvazuva kweCanada uye iri kuenda kuRussia. Hatifanire kukanganwa kuti yakasimba magineti kuchamhembe idanda rekumaodzanyemba.
Kukosha kwemagineti kudzora
Iyo kona mune yakatenderera ndege yakaumbwa nemagineti ekuchamhembe uye nenzvimbo yekuchamhembe. Iyi kona, iko kufambisa iyo magnetic kuchamhembe gore rega rega kwaizopawo kukosha kwayo. Izvo hazvisi chete zvinopesana nemakore asi nenzvimbo yatiri. Chimwe chezvikonzero nei nautical machati ane imwe kukosha ndeyekuti kune kuwedzera kwegore kana kuderera kweye kukosha kweiyo magnetic kuderera zvichienderana nenzvimbo yatiri.
Kuti tizive kukosha kwemagineti kudonhedza isu tinofanirwa kuziva kuti, kana iyo magnetic kuchamhembe iri kurudyi kweyechokwadi kuchamhembe, iyo magnetic kuderera yakanaka. Kune rimwe divi, kana magnetic kuchamhembe iri kuruboshwe rwechokwadi kuchamhembe, iyo magnetic kuderera ichave isina kunaka kukosha. Aya ndiwo maitiro patinoongorora maratidziro emvura tinokwanisa kuwana kukosha kwedenderedzwa rakapedza kudzidza pakati pe0 ne360 degrees uye izvo zvinoratidza kukosha kwekudzikira kwemagineti kwegore rechinyorwa cheiyi chati. Uye zvakare, inowanzo kuratidza kukosha kwekusiyana kwegore kweiyi magnetic kuderera zvichienderana nekufamba kwemagineti ekumaodzanyemba pole.
Kana isu tikawanza iyo yegore kusiyanisa kwemagineti kudzikira nemakore apfuura kubva muchinyorwa chechati kusvika nhasi tinogona kuve neicho chaihwo kukosha kweyakagadziriswa magineti kudzikisira. Nenzira iyi, hazvidi kuti gore rega rega isu titenge itsva nautical chati.
Ndinovimba kuti neruzivo urwu iwe unogona kudzidza zvakawanda nezve magnetic kuderera.
