Dhululubo Madhan Magnets – Qiimo jaban | Fullzen

Qiimaha magnetka dhululubo aad ayuu u kala duwanaan karaa iyadoo ku xiran dhowr arrimood:

1. Qalabka iyo Darajada
2. Baaxadda iyo Cabirka
3. Dahaarka
4. Tirada
5. Alaabta iyo Summada
6. Habaynta

Fadlan ogow in qiimuhu is bedeli karo muddo ka dib arrimo ay ka mid yihiin isbedbeddelka suuqa, isbeddelka saadka iyo baahida, iyo horumarinta hababka wax soo saarka. Si aad u hesho qiimo sax ah oo cusub oo loogu talagalay magnet-ka dhululubada gaarka ah ee aad xiisaynayso, waxaan ku talinayaa inaad ka hubiso alaab-qeybiyeyaasha magnetka, soo saarayaasha, ama tafaariiqda onlaynka ah.

qulqulka magnetic (
$\Phi$

Φ) dusha sare waxaa lagu bixiyaa qaacidada:

$\Phi =�\cdot �\cdot cos(�)$

Φ=B⋅A⋅cos(θ)

meesha:

• 
  $�$

  B waa xoogga goobta magnetic ( gudaha teslas, T).

• 
  $�$

  A waa bedka dusha sare oo u dhigma goobta birlabeedka (mitir laba jibaaran, m²).

• 
  $�$

  θ waa xagasha u dhaxaysa xadadka magnetic field iyo vector-ka caadiga ah ee dusha sare.

Magnet cylindrical-ka, xaaladdu waxay noqon kartaa mid ka sii adag sababtoo ah goobta magnetic had iyo jeer maaha mid joogto ah oogada oo dhan sababtoo ah kala duwanaanshaha magnetization gudaha dhululubada. Xaaladahan oo kale, waxaad u baahan doontaa inaad tixgeliso isku-dhafka magnetic field ee dusha sare si aad si sax ah u xisaabiso qulqulka magnetic.

Haddii goobta birlabku ay la mid tahay oo ay la siman tahay dhidibka dhululubada, waxa laga yaabaa in aad xaaladda fududayso oo aad isticmaasho qaacidada aan kor ku soo sheegnay. Si kastaba ha ahaatee, haddii aad la tacaalayso qaybinta goob magnetic ka sii qallafsan, waxaa laga yaabaa inaad u baahato inaad la shaqeyso fikrado aad u horumarsan, sida isku dhafka magnetic field vector ee dusha sare.

Silver caadi ahaan looma isticmaalo walxo si loo sameeyo birlab joogto ah, oo ay ku jiraan magnets cylinders. Magnets joogto ah, sida magnets neodymium (NdFeB), waxaa inta badan laga sameeyaa alloys ka kooban xubno sida neodymium, iron, iyo boron. Qalabkani waxay leeyihiin dhismayaal crystalline gaar ah oo gacan ka geysta sifooyinkooda magnetic xooggan.
