Le Imagnethi yomhlaba kunye neempawu zayo eziphambili

Enye yeempawu ezibalulekileyo bomzimba zombini bume oluntu yendalo neyenziweyo lo mhlaba otsalayo. Kuyinto oluthile lwe ubukho yentsimi electromagnetic. Eyona iphambili yale fom kukuba lo mhlaba otsalayo usebenza kuphela ezo amasuntswana kunye namaqumrhu, leyo, kwelinye icala, ke intshukumo oluzingileyo, kwaye kwelinye - aqulathe intlawulo ethile zombane.

Enye ikhosi ye physics siyazi ukuba adala imagnethi kuyimfuneko yangoku-Ukuthwala umqhubi kunye alternating zombane. Ezona mpawu zibalulekileyo kule bamasimi kuFacebook Imagnethi yomhlaba kunye namandla ngemagnethi.

Lo mhlaba otsalayo akha enye ubuninzi wesangqa ifundwa physics, equka umahluko yoqheliso kumda wesangqa magnetic kunye kumda wesangqa magnetization. Ekubeni ngobunzulu magnetic unalo kumda wesangqa ixabiso, ngoko iyunithi yayo yomlinganiselo kwi eliqhelekileyo kwaye ixhaphakileyo SI igqalwa amperes metre nganye. Ukuze ufumane i ngobunzulu intsimi magnetic kunye ubukhulu ka-1 / m, kuyimfuneko ukuba ngentambo eyandisiweyo rectilinear enobubanzi encinanana kangangoko flow electric kwicandelo yangoku 2π amp amandla. Kulo mzekelo zonke iingongoma ezenziwa ukuba magnetic intsimi langoku kwimitha 1 kunye umoya ngamandla intsimi ilingana 1 A / m.

Lo mhlaba otsalayo, ngamanye amazwi, inani imigca amandla yasendle ukuyiqikelela. Ngokukodwa, ukuze babone icala le migca, ungasebenzisa i kakuhle yaziwa phezu ulawulo ekunene-ngesandla. Lo mgaqo - enye yeemfundiso yonke zobunjineli yombane. Ithi kwandula ukuba orientation iyonke lobhontsi motion efana ngokupheleleyo indlela yangoku yombane umqhubi ethile, icala ukujikeleza lobhontsi efanayo ulwalathiso lwelayini emagneti.

Ukujolisa ngalo mgaqo, kulula ukungqina ukuba imigca sibubona ezifumaneka Akubuya ze Ikhoyili ziya kwicala elinye. Kulo kunokwenziwa isigqibo sokuba lo mhlaba otsalayo ngaphakathi Ikhoyili iya kuba babomelele ngakumbi ngobunzulu eziveliswa yena mnye. Oku kungenxa kuquka ukuba imigca amandla amagophe ezikufutshane kukho ukufana omnye komnye kumacala ahlukeneyo, ke ngoko, i-magnetic amandla endle phakathi kwabo baya ngokuthe ngcembe ndinciphe ke mna.

Kungokwemvelo ukuba lo mhlaba otsalayo of coil ngamnye kisekiyo ngqo ukomelela yangoku leyo udlula Akubuya. Ukongeza, i-magnetic amandla endle kuxhomekeke enoba ezi engathi zicwangciswe xa kuthelekiswa namanye. Empirically, icikidwa ukuba jiko ezimbini apho umbane yhuu amandla enye, kwaye inani amathuba lingqamane ngokupheleleyo, lo mhlaba otsalayo yomelele lowo apho Ikhoyili ubude yezihlunu ezincinci, ngamanye Akubuya ngakumbi kakhulu omnye komnye.

Enye yezinto ezibalulekileyo kakhulu lo mhlaba otsalayo lixabiso ngamanani ampere-amathuba, leyo ibalwe phinda inani amathuba kwi Ikhoyili ngamandla ngoku elibaleka kuzo. kunye nomkhosi magnetomotive iya kuxhomekeka kwixabiso ampere-amathuba. Ngokusekelwe kule mbono, kulula ukubonisa ukuba lo mhlaba otsalayo ukuba isifundo Ikhoyili umlinganiselo ngqo inani ampere-amathuba ngeyunithi ubude yezihlunu nganye. Ngamanye amazwi, le umoya ngamandla intsimi iphezulu, kokukhona ubuninzi amandla magnetomotive efunyenwe kuvavanyo coil.

Ngaphandle emasimini okwenziwe eyenziwe owahluke ngokwemvelo, kukho yendalo Imagnethi yomhlaba, oluthi luqokelelane kakhulu kwi iqokobhe olungaphandle ngumongo. iimpawu eziphambili kule intsimi, kuquka kwempixano, ziyahluka zombini ngexesha kunye nendawo, kodwa yonke imithetho ezisisiseko uphawu emasimini esidalwe ngumntu, kwaye asebenza kwintsimi geomagnetic.
