Amandla ensimu yamagnetic kanye nezici zayo eziyinhloko

Esinye sezici ezibaluleke kakhulu ezibonakalayo zomuntu wendawo nemvelo yokufakelwa yinkimbinkimbi. Imelela enye yezinto zokuba khona kwensimu ye-electromagnetic. Isici esiyinhloko esivela kule fomu ukuthi insimu magnetic yenza kuphela lezo zinhlayiya nemizimba ukuthi, ngakolunye uhlangothi, ihamba ngokuqhubekayo, futhi ngakolunye uhlangothi - iqukethe icala elithile kagesi.

Kuyaziwa futhi ngenkambo ye-physics ukuthi umqhubi onamasimu kagesi wamanje nokunye okudingekayo ukuze adle insimu yamagnetic. Izici ezibaluleke kakhulu kule nsimu yi-vector yokufakelwa kwamagnetic kanye ne-magnetic tension.

Amandla omhlaba wamagnetic ingenye yezinto eziningi ezifundwa ku-physics, ezihlanganisa umehluko we-electromagnetic induction vector, kanye ne-vector magnetization. Njengoba ukuvuthwa kwamagnetic kuyinto iningi vector, ngokuvamile kucatshangwa ukuthi unit yayo yokulinganisa ohlelweni oluvamile futhi ejwayelekile SI kuyinto ampere per meter. Ukuze uthole amandla ensimu kagesi kagesi ka-1 a / m, kuyadingeka ukuthi umbane kagesi we-2π ampere ugeleza ngetambo elandelwe kabusha elinezilinganiso ezincane kakhulu. Kulesi simo, kuwo wonke amaphuzu ensimu yamagnetic eyakhiwe yilo manje kude namamitha ayi-1, ukuqina komkhakha wamagesi futhi kuzoba ngu-1 a / m.

Ukuqina kwendawo yamagnetic, noma, ngamanye amazwi, inani lemigqa yamandla yale nsimu, kungalinganiselwa. Ikakhulukazi, ukuze kunqume ukuqondiswa kwale migqa, umuntu angasebenzisa umbuso owaziwayo we-borer. Le mithetho ingenye yamakhonkco azo zonke izinto zobuchwepheshe kagesi. Ithi lapho kwenzeka ukuthi ukuqondiswa okujwayelekile kokuhamba kwe-borer kufana ngokuphelele nokuqondiswa komshini kagesi kumqhubi othile, ukuqondisa kokujikeleza kwe-borer kufana nokuqondiswa kwemigqa yamagnetic.

Ukugxila kulo mthetho, kulula ukufakazela ukuthi imigqa yamagnetic eyenzeka ekushintsheni kwekhoyili iqondiswa ohlangothini olufanayo. Kusukela lokhu kungaphethelwa ukuthi ukuqina komkhakha wamagnetic ngaphakathi kwekhoyili kuyoba namandla kunokwakheka okudalwe ikhoyili eyodwa. Lokhu kubangelwa, phakathi kwezinye izinto, ukuthi imigqa yamandla okujika okuhambisana nendawo iyafana, kepha ngezindlela ezihlukene, ngakho-ke, ukuqina komkhakha wamagnetic phakathi kwabo kuzokwehla kancane.

Kungokwemvelo ukuthi insimu magnetic yanoma iyiphi i-coil ngokuqondile ngokulingana nobukhulu bamanje obudlula ngamakhoyili ayo. Ngaphezu kwalokho, ukuqina kwensimu yemagnetic ngokuqondile kuxhomeke ekutheni lezi ziphendulela zisondele kangakanani komunye nomunye. Kuboniswe isipiliyoni ukuthi ngamakhoyili amabili lapho umbane kagesi wamandla alinganayo ugeleza kanye nenombolo yokujika ihambelana ngokuphelele, insimu yamagnetic iyoqina nakakhulu lapho ikhoyili ine-axial ubude obuncane, okungukuthi, ukujika kwayo kutholakala kakhulu kakhulu komunye nomunye.

Isici esibaluleke kakhulu sensimu yamagnetic yinani lezinombolo zamamera, angabalwa ngokuphindaphinda inombolo yokujika ku-coil okwamanje egeleza kuwo. I-magnetomotive force nayo iyoxhomeka ebukhulu bama-amperes. Ukuthembela kulo mqondo, kungabonakaliswa kalula ukuthi insimu yamagilekhi yekhoyili ngaphansi kophenyo ihambisana ngokuqondile nenani le-ampere-turning per unit axial length. Ngamanye amazwi, ukuqina kwensimu ye-electromagnetic kwanda, ukukhudlwana ubukhulu bamandla amagnetomotive akhiqizwa ku-coil ngaphansi kophenyo.

Ngokungeziwe emasimini amakhulu amakhulu adalwe, kusekhona insimu yemvelo yemvelo , eyakhiwa, ikakhulukazi, egobolondo langaphandle le-nucleus. Izici eziyinhloko zale nsimu, kufaka phakathi ukungezwani, ziyahlukahluka kokubili ngesikhathi nesikhala, kodwa yonke imithetho eyisisekelo yamasimu adalwe futhi asebenza ensimini ye-geomagnetic.
