I-Cylinder 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 ozibuthe ngokufanayo eduze kwe-eksisi yayo emaphakathi ingalinganiswa kusetshenziswa ifomula yenkundla ngaphakathi kwe-solenoid. Lokhu kulinganiselwa kuthatha ukuthi isilinda side kakhulu kunobubanzi bayo. Ifomula ithi:

$�=�\cdot �$

B=μ⋅M

Kuphi:

• 
  $�$

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

  μ ukungeneka kwezinto (okungaguquki, ngokuvamile

  μ0​ yevacuum noma umoya, okulingana no

  I-M yimagnetization yesilinda (umzuzu kazibuthe ngevolumu yeyunithi ngayinye, ku-A/m).

Ukuze uthole isilinda ozibuthe ngokufanayo,

M ingabalwa ngokuthi:

$�=�isamba�isilinda$

M=Vcylinder Mtotal

Kuphi:

• 
  $�\; isiyonke$

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

• 
  $�isilinda$

  I-Vcylinder 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 ezingase ziholele embonweni wokuthi indawo kazibuthe inguziro ngaphakathi kwesilinda:

1. Ukuvikela
2. I-Uniform Magnetization

Kubalulekile ukuqaphela ukuthi indawo kazibuthe ngaphakathi kukazibuthe oyi-cylindrical izoncika ezintweni ezihlukahlukene, okuhlanganisa ukusatshalaliswa kukazibuthe, umumo kazibuthe, izici ezibonakalayo, namathonya angaphandle njengezinkundla kazibuthe eziseduze noma isivikelo. Ngokuvamile, amandla kazibuthe angabalwa futhi alingiswe ngokusekelwe kulezi zici, kodwa inkambu mancane amathuba okuba ibe uziro ngaphakathi kwesilinda ozibuthe ngokufanayo.

Yebo, kungaba khona insimu kazibuthe ngaphakathi kwesilinda esingenalutho, inqobo nje uma isilinda sinohlobo oluthile lokudonsa uzibuthe. Ubukhona nezici zenkundla kazibuthe ngaphakathi kwesilinda esingenalutho kuncike ezintweni ezifana nephethini yokuzibuthe, izici ezibonakalayo, kanye nejiyomethri 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. I-Demagnetized Hollow Cylinder
4. I-Magnetic Shielding Cylinder

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.
