Isiseko zobunjineli bombane mihla - isenzeko yoqheliso electromagnetic

Lo mkhuba yoqheliso magnetic kwi zobunjineli lombane kwisiseko. Kuye empirically yafunyanwa kwakhona ngo-1831 yi yamachiza IsiNgesi Michael Faraday. Nangona kwakusaziwa ukuba phakathi umqhubi kunye umazibuthe kufuphi ukusebenzisana kwenzeka. Oku kwakukholelwa ukuba intlawulo fixed ukusebenzisana nge esigangeni sombane, kwaye intshukumo yabo (current) lubonakala emasimini ngemagnethi. Noko ke, ithemba ngokoqobo olu lwazi iziphumo zovavanyo Faraday kaThixo ongacacanga kakhulu. Enyanisweni, i-nzulu eyafumana isenzeko yoqheliso magnetic, aphawula ukuqala ezisisiseko zobunjineli bombane mihla.

Amava ngokwawo pretty elula: ibhari umazibuthe esisigxina baqalisa ukuhamba, yaye wachongwa kwisikhewu engundoqo phakathi amathuba ye-coil. Iziphelo coil afakelwe isixhobo isivamvo zokulinganisa amaxabiso ezincinane olukhoyo kunye ombane.

Kuye waphawula ukuba xa uhambisa umazibuthe galvanometer inaliti kuphambuka ukusuka kwindawo kwiqanda. Kwaye ukuphambuka omkhulu, kwimagnethi isusiwe okukhulu. Ukuba khumbula ukuba inomgca kwipali amabini kunye namandla entsimini, kuba ulwalamano ocacileyo phakathi wobhobhozayo Imagnethi yomhlaba kunye yangoku uqhutyelwe wadalwa.

Ekubeni ngoku akakwazi okungacwangciswanga kwisekethe, kusengqiqweni ukugqiba le imbonakalo amandla electromotive yenziwa (EMF), mvisiswano leyo, kwelinye icala, likuvumela ukuba kwamkela yangoku. umthetho Faraday kaThixo yoqheliso kuvumela ukuba uchaze ukuba ifuthe ukuba umqhubi Imagnethi ezahlukahlukeneyo ngexesha lungunobangela yokutshintsha intsimi sombane kunye, ukuba ivaliwe yesekethe yangoku.

Lo mkhuba yoqheliso magnetic wamvumela ukuba enze isigqibo revolution ezibangela intsimi yombane kusenokungabikho kuphela iintlawulo kodwa ezahlukahlukeneyo zibuthe. Kamva laliqulunqwe gabalala. Ngoko ke, umthetho Faraday kaThixo yoqheliso magnetic, uthi: kudala magnetic EMF intsimi ixhomekeke ngqo kwi izinga utshintsho ngobhobhozo ngemagnethi. Amandla ye yangoku eveliswa yomtya evaliweyo ibalwa ngokomthetho Ohm kaThixo.

Lo mkhuba yoqheliso magnetic nto luphawu hayi kuphela umqhubi kodwa wamaziko ezinkulu conductive. Ngoko ke, lo ukutshintsha Imagnethi uvelisa umqhubi ubukhulu (ipleyiti zentsimbi njalo njalo.) Eddy kwemisinga. Balala zokufudumeza engafunwayo, ngoko ke iindlela ezahlukeneyo ezisetyenzisiweyo nya (in abaguquli plate laminations ngentsimbi zombane). Qaphela ukuba ezinye izixhobo, imisinga eddy zisetyenziswa (zokubala idiskhi accounting).

Kungekudala, ngowe-1833, yamachiza E. Lentz wakhokela umthetho, ngenxa yayo, EMF eyabangelwa uvelisa a sangoku myalelo Nokwethisa unobangela ngenkangeleko yakhe. Umzekelo: ukutshintsha Imagnethi ukhuthaza a zangoku nombhexeshi. It yenzelwe ukuze nemagnethi ngokwayo (zikhoyo malunga izinikezeli yangoku-ephethe) sonjululwa imbangela.

Lo mkhuba yoqheliso magnetic ukuba ukuphuhlisa ubunjineli ombane ukuya kwimo yazo yangoku. Kunzima ukubeka uluhlu olupheleleyo izixhobo isebenzisa. Umzekelo, umsebenzi umbane izityalo lwamandla kule meko. Nangona kunjalo, uyilo umthamo isizukulwana ithe utshintsho olukhulu ukususela Faraday, nangona kunjalo, umthetho-siseko jikelele uhlala efanayo; imigca lo mhlaba otsalayo yendlela yokwenza lo rhoqo engathi ekuqhutyweni ngoku, nto leyo amandla electromotive kunye, ukuba ombane loop ezivaliweyo. Ngaphezu koko umbane kunye Motors, kusetyenziswa induction nesenzeko, umz, xa abaguquli.
