The a khoheli e lumellang metsi ho kena ba ntho e

Kamano pakeng tsa le matla a khoheli (H) le e matla a khoheli ts'ebetsong segokanyipalo (B) ka lintho tse bonahalang tse e tšoauoa ka a mangata 'meleng bitsoa matla a khoheli e lumellang metsi ho kena. ka ho feletseng matla a khoheli e lumellang metsi ho kena ba mahareng - karo-karolelano ea B ho H. Ho ea ka System International tsa lihlopha e lekanngoa ka diyuniti bitsoa 1 Henry ka mitha.

A boleng dipalo tsena a bontša hore ke karo-karolelano ea boholo lona ho boholo ba e lumellang metsi ho kena lona a khoheli a ba lephaka le e denoted ke μ. boleng ena o bitsoa a lekanyelitsoeng a khoheli e lumellang metsi ho kena (kapa e lumellang metsi ho kena) ea mahareng ka. Kamoo ke mong ka bona, bo se na diyuniti.

Ka lebaka leo, a lekanyelitsoeng a khoheli e lumellang metsi ho kena μ - boleng bontsha makhetlo ba bakae tšimong ea induction ba mahareng e ka tlaase ho moo (kapa ho feta) ea lephaka induction matla a khoheli.

Ha o ile a pepesa ho ntho e, ho e ba magnetized ke ea tšimo Link a khoheli a. Hona see se etsahala? Ho ea ka khopolo ea Ampere, le leng le le taba ea ho lula ba e potoloha nyenyane maqhubu motlakase bakoang ke motsamao oa dieleketerone ka potoloha bona le ho ba teng ha bona matla a khoheli motsotso. Tlas'a maemo a tloaelehileng, mokhatlo oa sena ke disordered, 'me naha "timeng" (hlakola) e mong le tse ling. Ha tsamaisa 'mele ka tšimo Link le maqhubu a ntaela,' me 'mele o fetoha magnetized (m. E. Ho tšimo lona).

dintho tsohle tse e lumellang metsi ho kena ke fapaneng. E Thehiloe ho boleng ba lona, karohano moko-taba ka lihlopha tse tharo tse khōlō.

Ka boleng diamagnetic ea matla a khoheli e lumellang metsi ho kena μ - ea ka tlaasana ho a le mong. Mohlala, bismuth μ = 0,9998. Ke diamagnetic ke zinki, loto, quartz, lefika letsoai, koporo, khalase, hydrogen, benzene, metsi.

The a khoheli e lumellang metsi ho kena ya paramagnetic diyuniti kholoanyane hanyenyane (bakeng sa μ = 1,000023 aluminium). Mehlala ea paramagnetic - nikele, oksijene, tungsten, ebonite, polatinamo, naetrojene, moea.

Qetellong, sehlopha sa boraro e matleng a hae a 'maloa a dintho (haholo-holo tšepe le lits'epe tse kopantsoeng), eo ea matla a khoheli e lumellang metsi ho kena ke haholo (by ditaelo tse' maloa tsa boholo) feta bonngoe. Tsena dintho - ferromagnets. Ha e le hantle mona kenyeletsa nikele, tšepe, cobalt le lits'epe tse kopantsoeng tsa bona. Bakeng sa tšepe μ = 8 ∙ 10 ^ 3 bakeng sa motsoako nikele ea tšepe e μ = 2,5 ∙ 10 ^ 5. Ferromagnetic rua thepa eo khetholla ho tloha lintho tse ling. Pele, ba na le matla a khoheli a barrel. Tabeng ya bobedi, e lumellang metsi ho kena bona ke mosebetsi oa induction Link tšimo. Boraro, bakeng sa e mong le e ba bona ba na le mekhoa e itseng ea monyako mocheso, e bitsoang Curie ntlha eo e lahleheloang thepa lona ferromagnetic 'me e ba paramagnetic. Bakeng sa nikele Curie ntlha - 360 ° C, bakeng sa tšepe - 770 ° C.

The thepa ea ferromagnets rerang se feela e lumellang metsi ho kena, empa le ba boholo I, o ile a re e le magnetization ea ntho ena. Sena ke e rarahaneng e seng moleng mosebetsi wa induction a khoheli, khōlo e hlalosoa magnetization mola bitsoa magnetization mothinya. Ka tsela eo, kaha o fihla ntlha e itseng, e magnetization hoo e batlang e khaotsa ho ba eketsa (a khoheli ho tlala le hlaha). Backlog boleng ferromagnetic magnetization ho tswa ho tebile hakae ho hōla ya Link induction khoheli o bitsoa hysteresis. Tabeng ena, ho na le ke ho itšetleha ya ferromagnet tsa litšobotsi khoheli eseng feela ka boemo lona ka nako eo, empa hape ka magnetization lona pejana. Dikerafike setšoantšo sa mosebetsi ona mothinya o bitsoa hysteresis sekgoqetsane.

Ka lebaka la thepa ea lona, thepa ferromagnetic atisa ho sebelisoa tsebo. Ba li sebelisoa rotors tsa Motors le lijenereithara, ka tlhahisong ea cores transformer le phetela motlakase, ho tlhahisong ea lintho ea lik'homphieutha ea elektronike. The thepa khoheli ea thepa ferromagnetic li sebelisoa theipi e rekotang, lithelefono, theipi le lisebelisoa tse ling polokelo.
