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

Ukubala insimu yamagnetic (
$�$

B) ukuzungeza i-cylinder magnet kungaba yinkimbinkimbi kakhulu, kuye ngokusatshalaliswa kwe-magnetization ngaphakathi kwe-cylinder. Lapha, ngizochaza icala elilula lapho sine-cylinder ene-magnetization efanayo ene-axis yayo ye-magnetization ehambisana ne-axis ye-cylinder. Lokhu kuvame ukubizwa ngokuthi "i-cylinder ene-longitudinal magnetized."

Insimu yamagnetic (

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:

• 
  $�$

  I-B ingamandla ensimu yamagnetic endaweni engaphandle kwesilinda (ku-teslas, T).

• 
  $�$

  μ ukuvuleka kwezinto (okungaguquki, okuvamile
  $�0$

  μ0​ ye-vacuum noma umoya, elingana ne
  $4�\times 10-7$

  4π×10−7 T m/A).

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

Ukuze uthole isilinda esinozibuthe ofanayo,

I-M ingabalwa kanje:

$�=�isilinda\; esiphelele�$

M=Vcylinder​Isamba​

Kuphi:

• 
  $�isamba$

  I-Mtotal​ iyisikhathi esiphelele sikamaginethi sesilinda (ku-A m²).

• 
  $�isilinda$

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

Khumbula ukuthi lesi yisimo esilula futhi kungenzeka singameleli ngokunembile ukusatshalaliswa kwensimu yamagnetic ezimweni eziyinkimbinkimbi kakhulu. Uma i-magnetization ingalingani, noma uma ubukhulu besilinda bungakhulu kakhulu kunobubanzi bayo, izibalo ziba nzima kakhulu futhi zingadinga amasu ezinombolo noma okuhlaziya.

Ukuze uthole imiphumela enembile kakhudlwana, kungase kudingeke usebenzise izindlela ezithuthukisiwe ezifana nokulingisa ngezinombolo usebenzisa ukuhlaziywa kwezinto ezilinganiselwe noma izindlela zokuhlaziya ezicabangela izakhiwo zamagnetic zezinto kanye nokusatshalaliswa kwangempela kwamagnetization ngaphakathi kwesilinda.

Isitatimende sokuthi insimu yamagnetic ingu-zero ngaphakathi kwesilinda singase sibe ukungaqondi kahle noma ukwenza lula ngokweqile. Ngokuvamile, insimu yamagnetic ngaphakathi kwesilinda enozibuthe efanayo ayiyona u-zero. Kodwa-ke, kuye ngezimo ezithile kanye nokuqagela, kunezimo lapho insimu yamagnetic ngaphakathi kwesilinda ingaba buthakathaka noma ibonise izakhiwo ezithile ezingenza kubonakale sengathi insimu ayinamsebenzi.

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.

Insimu yamagnetic ngaphakathi nangaphandle kwemagnethi eyisilinda incike ezintweni ezahlukahlukene, okuhlanganisa iphethini yemagnetization, izakhiwo zezinto, kanye ne-geometry yesilinda. Ake sicabangele izimo ezimbalwa:

1. Isilinda Esinozibuthe Obufanayo
2. Isilinda Esinozibuthe Esinokukhanya Okubanzi
3. Isilinda Esingenalutho Esingenamagnethi
4. Isilinda Sokuvikela SikaMagnetic

Lezi izincazelo ezilula, futhi ukuziphatha kwangempela kwensimu yamagnetic kungaba yinkimbinkimbi kakhulu kuye ngezimo ezithile kanye nokuqagela. Empeleni, ukusatshalaliswa kwensimu yamagnetic kuvame ukuhlaziywa kusetshenziswa amamodeli ezibalo noma isofthiwe yokulingisa ecabangela izici ezinemininingwane zemagnet kanye nendawo ekuyo.
