Simba re magnetic field uye maitiro aro makuru

Chimwe chezvinhu zvakakosha mumamiriro ezvisikwa zvepanyama uye maitiro ekugadzira vanhu ndiyo magnetic field. Iyo inomiririra imwe yemhando dzehupenyu hwemagetsi emagetsi. Chinhu chikuru chinosiyanisa chimiro ichi ndechokuti magnetic field inoshanda chete pane izvo zvikamu uye miviri iyo, kune rumwe rutivi, iri mukuenderera mberi, uye kune imwe - ine imwe yemhosva yemagetsi.

Izvo zvinozivikanwawo kubva mumitambo yefizikiki iyo mutungamiri anezvino uye shanduko yemagetsi mashizha anodiwa kuti aumbe magnetic field. Zvinhu zvakakosha zvikuru maitiro emunda uyu ndeye vector ye magnetic induction uye magnetic tension.

Iyo magnetic field simba ndeimwe yevector yakawanda yakadzidza mufizikiki, inosanganisira musiyano we electromagnetic induction vector, uyewo magnetization vector. Sezvo magnetic tension ine vector yakawandisa, inowanzofungidzirwa kuti chiyero chekuyera mune imwe nzira yakakurumbira uye yakajairika yeSIM yakareba mamita. Kuti uwane simba rema electromagnetic simba re 1 a / m, zvakakosha kuti mhepo yegetsi ye 2π ampere inoyerera mumatare akareruka akareruka nechepamusoro-kati-chikamu chechidimbu. Muchiitiko ichi, pamativi ose emagnetic field akaumbwa neiyo ikozvino iri kure nemamita 1, kuwedzera kwemunda we electromagnetic uye ichava 1 a / m.

Izvo simba re magnetic field, kana nemamwe mazwi, nhamba yemiganhu ye simba rebindu iri, inogona kufungidzirwa. Kunyanya, kuitira kuti aone kutungamirirwa kwemitsara iyi, munhu anogona kushandisa mutemo unozivikanwa we borer. Uyu mutemo ndeimwe yemakona emakona eunjiniya wese. Iyo inotaura kuti kana chiitiko chekuti chinangwa chikuru chekufamba kwesimbi yakanyatsokwana zvakafanana nekutungamirirwa kwemagetsi emagetsi mune imwe mudzidzisi, mutungamiri wekutenderera wemuchina unofanana nehutungamiri hwemagetsi.

Kutarisa pamurairo uyu, zviri nyore kuratidza kuti maginito matsvene anowanikwa mukopi inotenderera anotungamirirwa kune rumwe rutivi. Kubva pane izvi zvinogona kugumiswa kuti kusimba kwemagnetic field mukati memoriya kuchave nesimba zvikuru kudarika kukonzerwa neketsi imwe chete. Izvi zvinokonzerwa, pakati pezvimwe zvinhu, kune chokwadi chokuti mitsara yekumanikidzwa kwepedyo inopindirana kune imwe neimwe, asi nenzira dzakasiyana, naizvozvo, kukwirira kwemagnetic field pakati pavo kuchaderera zvishoma nezvishoma.

Izvo zvakasikwa kuti magnetic field yepiil ipi neipi yakananga zvakananga nekukwirira kweiyo ikozvino inopfuura kuburikidza nemakumbo ayo. Mukuwedzera, kuwedzera kwemaginetic munda zvakananga kunoenderana nekuswedera kwatinoita kutendeuka kune mumwe nomumwe. Ive yakaratidzirwa nechiitiko icho mumakumbo maviri umo magetsi emagetsi eenzana akaenzana achiyerera uye nhamba inoshanduka yakanyatsobatana, magnetic field ichasimba mune imwe iyo coil inenge yakareba axial urefu, kureva kuti, kutendeuka kwayo kunowirirana zvikuru kune mumwe nemumwe.

Chinhu chakakosha zvikuru chemagnetic field ndiyo nhamba yepamusoro yei-amperes, iyo inogona kuverengwa kuburikidza nekuwedzera nhamba yekutendeuka mukati mekopi ikozvino iri kufamba mukati mavo. Iko magnetomotive simba richawedzerwawo nehukuru hwemasikeri. Zvichivimba nezveshoko iri, rinogona kuratidza nyore nyore kuti magnetic field ye coil iri pasi pekupfupiswa yakananga zvakananga nehuwandu hwemapere-turn per unit axial length. Mune mamwe mazwi, kuwanda kwemunda wegesi-electromagnetic kunowedzera, kuwedzera kwehukuru hwemagnetomotive simba rinobudiswa mukopi iri pasi pekuongorora.

Mukuwedzera pane zvakagadzirwa maginist masikati, kunezve masikirwo emagetsi emunyika, ayo akaumbwa, kunyanya, muhomwe yekunze kweyo nucleus. Izvo zvakakosha zvemunda uyu, kusanganisira kushungurudza, zvinopesana zvose munguva uye nzvimbo, asi mitemo yose yepamusoro inoratidzirwa nemasvingo akaumbwa anoshandawo mune geomagnetic field.
