Yintoni lo mhlaba otsalayo?

Yintoni lo mhlaba otsalayo? Ukuze siphendule lo mbuzo, makhe khumbula iziseko electrodynamics. Njengoko iyaziwa, phezu ebiphakathi ngecala carrier q, ukusukela kwindawo entsimini yombane elivelayo ukuhlela ukusebenza kunye nomkhosi F. Ixabiso isigxina ngaphezulu (kungakhathaliseki iimpawu zazo), kokukhona amandla. Le Ingxabano le - enye yeempawu yasendle. Ukuba unika njengendlela E, ngoko ke ufumana:

E = F / q

Kwelinye icala, iintlawulo mobile kuchaphazela lo mhlaba otsalayo wendalo. Noko ke, kule meko mandla kuxhomekeke nje kuphela ubuninzi kwentlawulo yombane, kodwa kwakhona indlela kumda wesangqa ye intshukumo (okanye, ngaphezulu kanye, isantya).

njani ukufunda uqwalaselo lo mhlaba otsalayo? Le ngxaki isonjululwe ngempumelelo izazinzulu ezaziwayo-kakuhle - Ampere kunye Oersted. Bona ibekwe kwisekethe umqhubi kunye ngobunzulu electric current kunye neziphumo ehlola yayinegunya. Kwathi kanti loo ndawo azinampembelelo ngenxa orientation nentaba ye esithubeni, ebonisa ubukho torque esiyua zokukhomba. Induction lo mhlaba otsalayo (kulinganiswa e Tesla) kubonakaliswa lomlinganiselo mzuzu wathi amandla ukuze imveliso ndawo yesekethe umqhubi kunye eliqukuqela yangoku yombane. Enyanisweni, ichaza intsimi ngokwayo, apho kulo mzekelo kuyimfuneko. Sonke Babonisa waxelelwa ngokusebenzisa indlela yokubala elula:

B = M / (S * I);

apho M - ixabiso liphezulu torque kuxhomekeke orientation yomtya imagnethi; S - indawo lilonke yomtya; I - zangoku nombhexeshi.

Ekubeni lo mhlaba otsalayo yi a ubuninzi yomzobo, oko Ngaphezulu kufuneka ukufumana orientation yayo. Umelo kakhulu olubonakalayo elinikeza inaliti eziqhelekileyo kusoloko ibonisa ukuba kwipali esentla. Imagnethi yomhlaba yoqheliso kaThixo orients ngokuvumelana imigca zibuthe. Into efanayo xa beka ikhampasi kufuphi umqhubi apho uhamba khona.

Ichaza wesekethe Fundisa ingqiqo mzuzu ngemagnethi. Le kumda wesangqa ngamanani lilingane imveliso S ukuya I. ulwalathiso lwayo aa-moya ezimiselweyo yomtya conductive. Ngaba kumiselwa yi ekunene ephaca eyaziwa Screw rule (okanye nakusithupha elifanayo). Induction lo mhlaba otsalayo kwi ukumelwa kumda wesangqa ingqamana indlela mzuzu ngemagnethi.

Ngaloo ndlela, kuyenzeka ukuba kuveliswe indlela kuba amandla ebambeleyo ekhankanyiweyo ndzhendzheleko (zonke izixa kumda wesangqa!):

M = B * m;

apho M - esiyua mzuzu lilonke amandla; B - kuFacebook magnetic; m - ixabiso mzuzu ngemagnethi.

Enye umdla zibuthe induction solenoid. Oku itankana ngenxeba ngocingo ecaleni apho umbane yhuu. Le yenye yezinto ezininzi ezisetyenziswayo Electrical Engineering. Kubomi bemihla ngemihla, kunye solenoids umntu ngamnye ujongene lonke ixesha, ngaphandle uyamazi kuyo. Ngoko ke, kwe sibubona yangoku ngaphakathi lombhobho na bomzi ngokupheleleyo, yaye kumda wesangqa yayo ngqo coaxially kunye lombhobho. Kodwa ngaphandle izindlu cylinder le induction otsalayo esiyua abangekhoyo (zero). Nangona kunjalo, oku kuyinyaniso kuphela ukuba coil iphelele ubude ongapheliyo. Ukuziqhelisa, umyinge ezahlukeneyo. Okokuqala, kumda wesangqa induction akusoze ilingana zero (endle kubhaliwe ngaphakathi ngeenxa lombhobho), kwaye uqwalaselo lwangaphakathi kwakhona uphelelwa ukufana yayo. Kutheni, ke ngoko, kufuneka i "isibonelo esiphelele"? elula kakhulu! Ukuba ngaphantsi kwe ubude ubukhulu cylinder (idla na), embindini yoqheliso kumda wesangqa solenoid phantse ngexesha elinye kunye nale modeli laka efanelekileyo. Ukwazi ububanzi nobude lombhobho, kunokwenzeka ukuba ukubala umahluko phakathi coil yoqheliso lokugqibela (engenasiphelo) nogxa yayo efanelekileyo. Oku kudla kuboniswa njengepesenti.
