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

Ukubala intsimi yemagnethi (
$�$

B) ukujikeleza imagnethi esilinda kunokuba nzima kakhulu, kuxhomekeke kukusasazwa kwemagnethi ngaphakathi kwesilinda. Apha, ndiza kuchaza imeko elula apho sine-cylinder enemagnethi efanayo ene-axis yayo yemagnethi ehambelana ne-axis yesilinda. Oku kudla ngokubizwa ngokuba yi-"cylinder enemagnethi ende."

Intsimi yamagnetic (
$�$

B) ngaphandle kwesilinda esinemagnethi efanayo ecaleni kwe-axis yayo ephakathi kunokuqikelelwa kusetyenziswa ifomula yentsimi engaphakathi kwi-solenoid. Olu qikelelo lucinga ukuba isilinda inde kakhulu kunobubanzi bayo. Ifomula yile:

$�=�\cdot �$

B=μ⋅M

Apho:

• 
  $�$

  I-B yi-magnetic field strength kwindawo engaphandle kwesilinda (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:

$�=�isilinda\; iyonke�$

M=Visilinda​Mtotal​

Apho:

• 
  $iyonke$

  I-Mtotal​ ngumzuzu opheleleyo wemagnethi wesilinda (kwi-A m²).

• 
  $�isilinda$

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

Khumbula ukuba le yimeko elula kwaye isenokungabonisi ngokuchanekileyo ukusasazwa kwemagnethi kwiimeko ezinzima ngakumbi. Ukuba imagnethi ayifani, okanye ukuba ubukhulu besilinda abubukhulu kakhulu kunobubanzi bayo, izibalo ziba nzima ngakumbi kwaye zinokufuna iindlela zokubala okanye zokuhlalutya.

Ukuze ufumane iziphumo ezichanekileyo, kunokufuneka usebenzise iindlela eziphambili ezifana nokulinganisa amanani usebenzisa uhlalutyo lwezinto ezilinganiselweyo okanye iindlela zohlalutyo eziqwalasela iimpawu zemagnethi zezinto kunye nokusasazwa kwemagnethi yokwenyani ngaphakathi kwesilinda.

Ingxelo yokuba intsimi yemagnethi ingu-zero ngaphakathi kwesilinda isenokuba kukungaqondani okanye ukwenza lula kakhulu. Ngokubanzi, intsimi yemagnethi ngaphakathi kwesilinda enemagnethi efanayo ayingu-zero. Nangona kunjalo, ngokuxhomekeke kwiimeko ezithile kunye neengqikelelo, kukho iimeko apho intsimi yemagnethi ngaphakathi kwesilinda inokuba buthathaka okanye ibonise iimpawu ezithile ezinokwenza kubonakale ngathi intsimi ayinamsebenzi.

Nazi iimeko ezimbalwa ezinokukhokelela kwingcamango yokuba intsimi yamagnetic ayingeni 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.

Intsimi yemagnethi ngaphakathi nangaphandle kwemagnethi esilinda ixhomekeke kwizinto ezahlukeneyo, kuquka ipateni yemagnethi, iimpawu zezinto, kunye nejometri yesilinda. Makhe siqwalasele iimeko ezimbalwa:

1. Isilinda esineMagneti efanayo
2. Isilinda esineMagneti ebanzi
3. Isilinda Esingenanto Esingenamagnethi
4. Isilinda sokukhusela seMagnetic

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.
