Ukubhobhoza magnetic

Ukusebenzisa umgca amandla, hayi kuphela ukubonisa indlela lo mhlaba otsalayo, kodwa ukuchaza ubukhulu yoqheliso yayo.

Siye amalungiselelo yokwenza imigca amandla ukuze 1 cm² indawo nkqo induction kumda wesangqa kwindawo ethile, inani lee layini ezithe zabanjwa elilinganayo amandla entsimini ngelo xesha.

Kule ndawo apho aya kuba mkhulu amandla intsimi, imigca endle ziyatyeba. Kwelinye icala, apho amandla endle umgca amandla kancinci kancinci.

Ngenxa yoko, lexinene migca mhlaba otsalayo baya kugwetywa kwi yayo ubukhulu yoqheliso kumda wesangqa kunye ulwalathiso imigca force - le ulwalathiso kumda wesangqa.

Ukuqwalasela jiko spectra magnethi yangoku ngqo ibonisa ukuba ukususwa umqhubi lo mhlaba otsalayo unciphisa, koko, ngokukhawuleza kakhulu.

Imagnethi yomhlaba kunye induction olungalinganiyo kwiindawo ezahlukeneyo ekuthiwa owahlukeneyo. Field i intsimi nonuniform yi endle rectilinear nesangqa seenketho lwangoku ngaphandle solenoid, intsimi le umazibuthe isigxina , njl

Lo mhlaba otsalayo iyafana kuzo zonke iingongoma yoqheliso yi endle eyohlobo olulodwa. zibuthe ngokwegrafu yohlobo olunye zimelwe imigca endle leswaku amele ngokulinganayo abekwe akwimiganyana imigca ngaxeshanye.

Umzekelo yentsimi uniform ke intsimi ukuya ingaphakathi coil elide, kwakunye entsimini phakathi kakhulu-bebekwe ngokwahlukeneyo omnye parallel ubuso kwipali Planar le electromagnet.

Imveliso lo mhlaba otsalayo luchukumisa yesekethe esisebenzayo kwindawo wesiphaluka kuthiwa wobhobhozayo kazibuthe kuFacebook Imagnethi okanye ukumpompoza nje ngemagnethi.

Ukuzimisela wamnika waza wafunda iimpawu yamachiza IsiNgesi - Faraday. Wafumanisa ukuba le nto yenza kube lula ukuba siqwalasele ngakumbi uhlobo ohlangeneyo le nesenzeko Imagnethi yomhlaba kunye zombane.

Aveza wobhobhozayo otsalayo yileta F, le ndawo aya S kunye engile ephakathi kwicala kumda wesangqa yoqheliso B kunye n yesiqhelo ukuya α kwindawo ngokwenzekayo, inxaki ilandelayo kubhalwa:

F = B S cos α.

ekubhobhozeni Magnetic - yinto inani scalar.

Ekubeni lexinene imigca amandla mhlaba otsalayo engenasizathu ilingana induction yayo, wobhobhozayo magnethi ngokulinganayo yonke inani imigca amandla engena sekethe esebenzayo.

Ngenxa utshintsho entsimini nenguqulo wobhobhozayo magnetic leyo ingena kwisekethe: intsimi yokukhulisa kwenyusa xa bezikhulule - ucutho.

Iyunithi ngobhobhozo otsalayo kwi SI wafumana umsinga leyo ingena ummandla we-1 m² yaye entsimini yohlobo olunye ngemagnethi kunye yoqheliso 1 WB / m², kwaye nkqo eya kumda wesangqa yoqheliso. Loo iyunithi kuthiwa Weber

1 WB = 1 WB / m² ˖ 1 m².

Utshintsha ukumpompoza nemagnethi kudala intsimi yombane ukuba imigca amandla zivaliwe (omtsha intsimi zombane). Le endle ivela kwi Windows Explorer njengoko isenzo imikhosi amazwe. Le nto ibizwa ngokuba yoqheliso magnetic, kunye nomkhosi electromotive eveliswa ngexesha elinye - EMF induction.

Ngaphezulu, kufuneka kuqatshelwe ukuba wampompoza nosiba kwenza kube lula ukuchaza ii-umazibuthe uwonke wonke (okanye nayiphi na eminye imithombo zemagneti). Ngoko ke, ukuba loxinano magnethi obhobhozayo kwenza kube lula ukuchaza iziphumo zayo kuyo nayiphi na indawo enye, wobhobhozayo magnetic - xa iyonke. Oko kukuthi, kunokuthiwa ukuba lo nguye iimpawu yesibini lubalulekileyo mhlaba otsalayo. Ngenxa yoko, ukuba loxinano magnethi obhobhozayo isebenza uphawu amandla lo mhlaba otsalayo, wobhobhozayo magnetic - kuba iimpawu zayo amandla.

Ukubuyela kule amava, nathi sithi yonke ekujikeni Ikhoyili nga bacinge njenge ngokwahlukileyo yazeka ijika elikhohlakeleyo. Ezikwisekethe enye, apho uya kudlula wobhobhozayo kazibuthe kuFacebook ngemagnethi. Kwimeko enjalo uya kumakishwa umbane kuFacebook. Ngenxa yoko, uphantsi kweempembelelo obhobhozayo magnetic amasimi efunyenwe zombane umqhubi closed. Kwaye ke lo mhlaba yombane ivelisa umsinga wombane.
