I-Silinda Neodymium Magnet 6*13mm – Isampula Yamahhala Iyatholakala | I-Fullzen

Ibala inkambu kazibuthe (

B) nxazonke zikazibuthe oyi-cylindrical kungaba yinkimbinkimbi, kuye ngokusabalalisa kukazibuthe ngaphakathi kwesilinda. Lapha, ngizochaza ikesi eyenziwe lula lapho sinesilinda ozibuthe ngokufanayo ne-eksisi yamagnetization eqondaniswe ne-axis yesilinda. Lokhu kuvame ukubizwa ngokuthi "isilinda esinezibuthe eside."

Insimu kazibuthe (

B) ngaphandle kwesilinda esinozibuthe ofanayo eceleni kwe-axis yaso ephakathi kungalinganiswa kusetshenziswa ifomula yensimu engaphakathi kwe-solenoid. Lokhu kulinganiselwa kucabanga ukuthi isilinda side kakhulu kunobubanzi baso. Ifomula ithi:

$�=�\cdot �$

I-B=μ⋅M

Kuphi:

•

  B amandla kazibuthe endaweni engaphandle kwesilinda (ku-teslas, T).

  I-M iyi-magnetization yesilinda (umzuzu wamagnetic ngevolumu yeyunithi ngayinye, ku-A/m).

Ukuze uthole isilinda ozibuthe ngokufanayo,

I-M ingabalwa kanje:

$�=�isamba�isilinda$

M=Vcylinder Mtotal

Kuphi:

• 
  $�isamba$

  I-Mtotal yisamba somzuzu kazibuthe wesilinda (ku-A m²).

• 
  $�isilinda$

  Isilinda esingu-V yivolumu yesilinda (ku-m³).

Khumbula ukuthi lesi yisimo esenziwe lula futhi singase singameli ngokunembile ukusatshalaliswa kwenkundla kazibuthe ezimweni eziyinkimbinkimbi kakhulu. Uma i-magnetization ingafani, noma uma ubukhulu besilinda bukhulu kakhulu kunobubanzi bayo, izibalo ziba nzima kakhulu futhi zingadinga amasu ezinombolo noma okuhlaziya.

Ukuze uthole imiphumela enembe kakhudlwana, ungase udinge ukusebenzisa izindlela ezithuthukisiwe ezifana nezifaniso zezinombolo usebenzisa ukuhlaziya izinto ezinomkhawulo noma izindlela zokuhlaziya ezicabangela izici kazibuthe zezinto kanye nokusabalalisa kwangempela kozibuthe ngaphakathi kwesilinda.

Isitatimende sokuthi indawo kazibuthe inguziro ngaphakathi kwesilinda singase sibe ukungaqondi kahle noma ukwenza lula ngokweqile. Ngokuvamile, inkambu kazibuthe ngaphakathi kwesilinda ozibuthe ngokufanayo ayiyona iqanda. Kodwa-ke, kuye ngezimo ezithile kanye nokuqagela, kunezimo lapho inkambu kazibuthe ngaphakathi kwesilinda ingaba buthakathaka ngokuqhathaniswa noma ibonise izici ezithile ezingenza kubonakale sengathi inkambu ayinaki.

Nazi izimo ezimbalwa ezingaholela embonweni wokuthi insimu yamagnetic ayi-zero ngaphakathi kwesilinda:

1. Ukuvikela
2. Ukwenziwa Kwamaginethi Okufanayo

Kubalulekile ukuqaphela ukuthi insimu yamagnetic ngaphakathi kumagnet esilinda izoncika ezintweni ezahlukahlukene, okuhlanganisa ukusatshalaliswa komagnetization, ukuma kumagnet, izakhiwo zezinto ezibonakalayo, kanye nethonya langaphandle njengezinkundla zamagnetic eziseduze noma ukuvikela. Ngokuvamile, amandla ensimu yamagnetic angabalwa futhi alingiswe ngokusekelwe kulezi zici, kodwa insimu cishe ayinakuba yi-zero ngaphakathi kwesilinda esinomagnethi efanayo.

Yebo, kungaba khona insimu yamagnetic ngaphakathi kwesilinda esingenalutho, uma nje isilinda sinohlobo oluthile lwe-magnetization. Ukuba khona kanye nezici zensimu yamagnetic ngaphakathi kwesilinda esingenalutho kuncike ezintweni ezifana nephethini ye-magnetization, izakhiwo zezinto, kanye ne-geometry yesilinda.

Inkambu kazibuthe ngaphakathi nangaphandle kukazibuthe oyisilinda incike ezintweni ezihlukahlukene, okuhlanganisa iphethini yamagnetization, izakhiwo zezinto ezibonakalayo, kanye nejiyomethri yesilinda. Ake sicabangele izimo ezimbalwa:

1. I-Uniformly Magnetized Cylinder
2. I-Radially Magnetized Cylinder
3. Isilinda Esingenalutho Esingenamagnethi
4. Isilinda Sokuvikela SikaMagnetic

Lezi yizincazelo ezenziwe lula, futhi ukuziphatha kwangempela kwendawo kazibuthe kungaba yinkimbinkimbi kuye ngezimo ezithile kanye nokuqagela. Empeleni, ukusatshalaliswa kwenkundla kazibuthe kuvame ukuhlaziywa kusetshenziswa amamodeli ezibalo noma isofthiwe yokulingisa ecabangela izici ezinemininingwane zikazibuthe nendawo yawo.
