Iimagnethi zeSilinda eziHollow – Ngexabiso eliphantsi | Fullzen

Iindleko zemagnethi yesilinda zinokuhluka ngokubanzi ngokuxhomekeke kwizinto ezininzi:

1. Izinto eziphathekayo kunye neBanga
2. Ubungakanani kunye nemilinganiselo
3. Ukwaleka
4. Ubungakanani
5. Umthengisi kunye neBrand
6. Ukwenza ngokwezifiso

Nceda uqaphele ukuba amaxabiso anokutshintsha ngokuhamba kwexesha ngenxa yezinto ezifana nokuguquguquka kweemarike, utshintsho kubonelelo kunye nemfuno, kunye nokuqhubela phambili kwiinkqubo zokuvelisa. Ukufumana ixabiso elichanekileyo nelihlaziyiweyo lemagnethi ethile onomdla kuyo, ndicebisa ukuba ujonge kubathengisi bemagnethi, abavelisi, okanye abathengisi be-intanethi.

Umbane wemagnethi (
$\Phi$

Φ) ngomphezulu unikwa ngefomula:

$\Phi =�\cdot �\cdot cos(�)$

Φ=B⋅A⋅cos(θ)

apho:

• 
  $�$

  B ngamandla ombane wemagnethi (kwi-teslas, T).

• 
  $�$

  A ngummandla womphezulu othe ngqo kumhlaba wemagnethi (kwimitha yesikwere, m²).

• 
  $�$

  θ yiengile phakathi kwemigca yomhlaba wemagnethi kunye nevektha eqhelekileyo kumphezulu.

Kwizibuthe zecylindrical, imeko inokuba intsonkothe ​​ngakumbi ngenxa yokuba umhlaba wemagnethi awusoloko uguquguquka kumphezulu wonke ngenxa yeeyantlukwano kumagnetization ngaphakathi kwicylinder. Kwiimeko ezinjalo, kuya kufuneka uthathele ingqalelo ukudityaniswa komhlaba wemagnethi ngaphezulu komphezulu ukubala ngokuchanekileyo ukuqukuqela kwamagnetic.

Ukuba i-magnetic field ifana kwaye ihambelana ne-axis ye-cylinder, unokukwazi ukwenza lula imeko kwaye usebenzise ifomula ekhankanywe ngasentla. Nangona kunjalo, ukuba ujongene nokusasazwa kwemagnethi entsonkothileyo, kunokufuneka usebenze ngeekhonsepthi eziphambili, ezinjengokudibanisa i-vector yamandla kazibuthe ngaphezulu komphezulu.

SIilver ayiqhelekanga ukusetyenziswa njengesixhobo sokwenza iimagnethi ezisisigxina, kubandakanya imagnethi yesilinda. Iimagnethi ezisisigxina, ezifana nemagnethi ye-neodymium (NdFeB), zihlala zenziwe kwii-alloys eziqulethe izinto ezifana neodymium, intsimbi kunye ne-boron. Ezi zixhobo zinezakhiwo ezithile ze-crystalline ezifaka isandla kwiimpawu zabo ezinamandla zamagnetic.
