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 kwesixhobo (isigxina, rhoqo
  $�0$

  μ0 yevacuum okanye umoya, ilingana ne
  $4�\times 10-7$

  4π×10−7 T m/A).

• 
  $�$

  I-M yimagnetization ye-cylinder (umzuzu wamagnetic kwiyunithi yeyunithi, kwi-A / m).

Kwisilinda enemagnethi efanayo,
$�$

M ingabalwa ngolu hlobo:

$�=�itotali�isilinda$

M=Vcylinder Mtotal

Apho:

• 
  $�\; iyonke$

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

• 
  $�isilinda$

  I-Vcylinder ngumthamo we-cylinder (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. I-Magnetization efanayo

Kubalulekile ukuqaphela ukuba umhlaba wemagnethi ngaphakathi kwemagnethi yecylindrical uya kuxhomekeka kwizinto ezahlukeneyo, kubandakanya ukuhanjiswa kwemagneti, ubume bemagnethi, iipropathi zezinto ezibonakalayo, kunye neempembelelo zangaphandle ezifana nemimandla yemagnethi ekufutshane okanye ukukhusela. Ngokubanzi, amandla omhlaba wemagnethi anokubalwa kwaye afaniswe ngokusekwe kwezi zinto, kodwa intsimi ayinakwenzeka ukuba ibe nguziro ngqo ngaphakathi kwicylinder enemagnethi efanayo.

Ewe, kunokubakho umhlaba wemagnethi ngaphakathi kwesilinda esingenanto, ngaphandle kokuba isilinda sinohlobo oluthile lwemagneti. Ubukho kunye neempawu zemagnethi ngaphakathi kwesilinda esingenanto zixhomekeke kwizinto ezifana nepateni yemagnetization, iipropathi zezinto eziphathekayo, 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 esineMagnetized Radially
3. I-Demagnetized Hollow Cylinder
4. I-Magnetic Shielding Cylinder

Ezi ziingcaciso ezilula, kwaye eyona ndlela yokuziphatha yemagnethi inobunzima ngokuxhomekeke kwiimeko ezithile kunye neengqikelelo. Ngokwesiqhelo, ukuhanjiswa kwemagnethi kudla ngokuhlalutywa kusetyenziswa iimodeli zemathematika okanye isoftware yokulinganisa ethathela ingqalelo iimpawu ezineenkcukacha zemagnethi kunye nokusingqongileyo.
