Imisinga ukusabela babashayeli parallel

ukuxhumana yamanje kahle kakhulu eyaziwa kwezobunjiniyela yesimanje kagesi:-ke ku-akhawunti lapho ukuklama eyinkimbinkimbi ezindaweni zamandla enunzi we "Tokamak" namadizayini kagesi. Ngokwesibonelo, esikhathini esidlule, shift ematfuba eduze we stator emazombezombe ukuze Rotor emazombezombe. Ngakho, lapho "ezisinda" kangaka ukuqala imishini enamandla lapho wamanje ifinyelela esiphezulu amagugu kuvunyelwe, umonakalo we ubambe shpug emazombezombe kungabonakala nasemkhakheni. Kulokhu kukhona ukuxhumana kazibuthe phakathi imisinga egeleza ngokusebenzisa Windings ezimbili ezihlukene. ujikelezisa amasimu abo kazibuthe kunethonya isenzo edonsa ku babashayeli. Ukutadisha nokuxhumana imisinga, ke ubhekwa nokuxhumana uhlobo kazibuthe, eqinisweni isihloko ethé xaxa.

Cabanga inethiwekhi ezintathu okhombisa, umugqa zazo axhumene iqembu lalo umthengi. Nakuba ukumelana yabo Imininingwane okungenani zilingana elibhekisela kuso sonke isimiso uqinile, kodwa okubiza kakhulu ukucasula kokusele imisinga siyeza imodi ngokuthi "isigaba skew" angalimaza iyunithi. Futhi imisinga ukuxhumana kwenzeka ngokuxhumeka okucishe kufane nalokhu ugesi okuningi umthwalo efanayo. Kulokhu, uma ukwehlukaniswa izigaba wenziwa ngendlela efanele, kukhona ukugeleza imisinga phakathi imithombo (ukusho kafushane), kodwa yi-non isigaba imigqa etholwe Ukunciphisa isekhethi. Ngokusobala, nokuxhumana imisinga kuzibonakalisa ngezindlela ezahlukene. Nokho kaningi kunakuqala ngokuvamile kubhekwa umthetho Ampere sika.

Uma phakathi izigxobo okuphambene uzibuthe (static kazibuthe) ibekwe Uhlaka ezithathekayo, okuyothi ngalo yamanje, sizophenduka a engela ezithile kunqunywa amandla nokuxhumana izinkambu ezimbili magnetic kanye imigqa ngamakhasimende ukungezwani. La mandla enza umzimba wayezimisele futhi washayelwa e 1820 by odumile French physics A. M. Amperom.

Njengamanje, sisebenzisa kumagama ezilandelayo: uma zamanje kugeleza umqhubi kwesigaba mncane e kazibuthe, amandla DF, sinomthelela endaweni ethile (dl) ngocingo, kuyinto ngokulingana ngqo ngamandla wamanje mina umkhiqizo Vector ubude dl e enanini lokungeniswa kazibuthe B. Lokho:

DF = (mina dl) * B,

lapho F, l, B - vector kobukhulu.

Icacisa isiqondiso F ngokuvamile eyenziwa ngendlela lelula - sobunxele umthetho. Engqondweni ingalo kwesokunxele kumele kahle ukuze umugqa ukungezwani we lokungeniswa kazibuthe (B) kufakwe isandla evulekile i-engela 90 degrees, 4 kuyalungiswa umunwe ekhombe isiqondiso zamanje (kusuka "+" ukuze "-"), khona-ke izimisele at engele kwesokudla isithupha ukhombise isiqondiso esebenza samanje aphethe umqhubi Ampere amandla.

Owaziwa kakhulu ngoba ngamandla nokuxhumana imisinga ngokulinganisa. Eqinisweni, lena yintfo lekhetsekile umthetho jikelele. Mela babashayeli ezimbili parallel samanje vacuo, ubude baso akunakulinganiswa. Ibanga phakathi kwazo luchazwa «r» incwadi. Umqhubi ngamunye (imisinga I1 futhi I2) yakha kazibuthe azungeze ngokwayo, ngakho basebenzisane. lokungeniswa imigqa imibuthano.

I isiqondiso magnetic lokungeniswa zithwala B1 kunqunywa wesithupha. Nangu ifomula:

B1 = (m0 / 4Pi) * (2 * I1 / r);

lapho m0 iyona njalo kazibuthe; r - ibanga; Pi - 3,14.

Ukusebenzisa ifomula okuthola Ampere amandla, sithola:

dF12 = (I2 * dl) * B1;

lapho dF12 - umthelela force ensimini umqhubi 1 ku umqhubi 2.

Amandla Module kuyinto:

dF12 = (m0 / 4Pi) * (2 * I1 * I2 / r) * dl.

Uma l obuphelele kulingana zero komunye bese:

F12 = (m0 / 4Pi) * (2 * I1 * I2 / r).

Lokhu ungamandla enza ethile iyunithi ubude zamanje esithwele wire. Uma wazi ukubaluleka F, kungenzeka ukwakha okuthembekile izimoto kagesi, ekunikezeni Ampere amandla. Iphinde isetshenziselwe ukubala njalo kazibuthe. Kuyadingeka ukuba uqaphele ukuthi, ngokusekelwe imithetho sobunxele, kusobala ukuthi uma lo mkhuba wamanje kuyafana, babashayeli basondela futhi uma kungenjalo - bacasulwa.
