I-Cylinder Neodymium Magnet 6*13mm – Isampulu yasimahla iyafumaneka | Fullzen

Ukubala umhlaba wemagnethi (
$�$

B) ujikeleze umazibuthe wecylindrical unokuba nzima kakhulu, kuxhomekeke kulwabiwo lwemagneti ngaphakathi kwesilinda. Apha, ndiza kuchaza imeko eyenziwe lula apho sine-cylinder enemagnethi efanayo kunye ne-axis yayo yemagnetization ehambelana ne-cylinder's axis. Oku kudla ngokubizwa ngokuba yi "cylinder longitudinally magnetized cylinder."

Umhlaba wemagnethi (
$�$

B) ngaphandle kwecylinder enemagnethi efanayo ecaleni kweasi esembindini inokuqikelelwa kusetyenziswa ifomula yentsimi ngaphakathi kwesolenoid. Olu qikelelo luthatha ukuba i-cylinder ide kakhulu kunobubanzi bayo. Ifomula yile:

$�=�\cdot �$

B=μ⋅M

Apho:

• 
  $�$

  B ngamandla ombane wemagnethi kwinqanaba elingaphandle kwe-cylinder (kwi-teslas, T).

• 
  $�$

  μ kukungena kwezinto (okungaguqukiyo, rhoqo
  $�0$

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

  4π×10−7 T m/A).

• 
  $�$

  I-M yimagnetization yesilinda (umzuzu wemagnethi ngeyunithi yevolumu, kwi-A/m).

Kwisilinda enemagnethi efanayo,
$�$

U-M unokubalwa ngolu hlobo:

$�=�itotali�isilinda$

M=Vcylinder Mtotal

Apho:

• 
  $iyonke$

  I-Mtotal ngumzuzu opheleleyo wemagnethi we-cylinder (kwi-A m²).

• 
  $�isilinda$

  Isilinda se-V yivolumu yesilinda (kwi-m³).

Gcina ukhumbula ukuba le yimeko eyenziwe lula kwaye inokungameli ngokuchanekileyo usasazo lwemagnethi kwiimeko ezinzima ngakumbi. Ukuba imagneti ayifani, okanye ukuba imilinganiselo yesilinda ayikho nkulu kakhulu kunodayamitha yayo, izibalo ziba yinkimbinkimbi kwaye zinokufuna ubuchule bamanani okanye uhlalutyo.

Ukufumana iziphumo ezichaneke ngakumbi, kunokufuneka usebenzise iindlela eziphucukileyo ezinje ngokulinganisa kwamanani kusetyenziswa uhlalutyo lwezinto ezinomda okanye iindlela zohlalutyo ezithathela ingqalelo iipropathi zemagneti zemathiriyeli kunye nokuhanjiswa kwemagnethi yokwenyani ngaphakathi kwesilinda.

Inkcazo yokuba umhlaba wemagnethi nguziro ngaphakathi kwesilinda inokuba kukungaqondi kakuhle okanye ukwenza lula kakhulu. Ngokubanzi, umhlaba wemagnethi ngaphakathi kwecylinder enemagnethi efanayo ayingoziro. Nangona kunjalo, kuxhomekeke kwiimeko ezithile kunye neengcinga, kukho iimeko apho i-magnetic field ngaphakathi kwe-cylinder inokuba buthathaka okanye ibonise iimpawu ezithile ezinokuthi zenze ukuba kubonakale ngathi intsimi ayinanto.

Nazi iimeko ezimbalwa ezinokukhokelela kumbono wokuba umhlaba wemagnethi unguziro ngaphakathi kwesilinda:

1. Ukukhusela
2. Ukwenziwa kweMagnetizer efanayo

Kubalulekile ukuqaphela ukuba intsimi yemagnethi engaphakathi kwimagnethi esilinda iya kuxhomekeka kwizinto ezahlukeneyo, kubandakanya ukusasazwa kwemagnethi, imilo yemagnethi, iimpawu zezinto, kunye neempembelelo zangaphandle ezifana nemimandla yemagnethi ekufutshane okanye ukhuselo. Ngokubanzi, amandla entsimi yemagnethi anokubalwa kwaye alinganiswe ngokusekelwe kwezi zinto, kodwa intsimi ayinakwenzeka ukuba ibe zero ngqo ngaphakathi kwesilinda enemagnethi efanayo.

Ewe, kunokubakho intsimi yemagnethi ngaphakathi kwesilinda esingenanto, ukuba isilinda inohlobo oluthile lwemagnethi. Ubukho kunye neempawu zentsimi yemagnethi ngaphakathi kwesilinda esingenanto zixhomekeke kwizinto ezifana nephethini yemagnethi, iimpawu zezinto, kunye nejometri yesilinda.

Umhlaba wemagnethi ngaphakathi nangaphandle kwemagnethi yecylindrical ixhomekeke kwizinto ezahlukeneyo, kubandakanya ipateni yemagneti, iipropathi zezinto ezibonakalayo, kunye nejometri yesilinda. Makhe siqwalasele iimeko ezimbalwa:

1. I-uniformly Magnetized Cylinder
2. Isilinda esineMagneti ebanzi
3. Isilinda Esingenanto Esingenamagnethi
4. I-Magnetic Shielding Cylinder

Ezi ziingcaciso ezilula, kwaye indlela esebenza ngayo i-magnetic field inokuba nzima kakhulu ngokuxhomekeke kwiimeko ezithile kunye neengqikelelo. Ngokwenyani, ukusasazwa kwe-magnetic field kudla ngokuhlalutywa kusetyenziswa iimodeli zezibalo okanye isoftware yokulinganisa ethathela ingqalelo iimpawu ezineenkcukacha ze-magnet kunye nokusingqongileyo.
