Xisaabinta goobta birlabta (
$�$

B) hareeraha birlabta dhululubada ah waxay noqon kartaa mid aad u adag, iyadoo ku xiran qaybinta birlabta ee ku jirta dhululubada. Halkan, waxaan ku qeexi doonaa kiis fudud oo aan ku leenahay dhululubo birlabaysan oo siman oo leh dhidibka birlabta oo la jaanqaadaya dhidibka dhululubada. Tan waxaa badanaa loogu yeeraa "dhululubo birlabaysan oo dherer ahaan la dheereeyay."

Goobta birlabta (

B) meel ka baxsan dhululubo birlabaysan oo siman oo ku teedsan dhidibka dhexe waxaa lagu qiyaasi karaa iyadoo la isticmaalayo qaacidada loogu talagalay goobta gudaha solenoid. Qiyaastani waxay u qaadanaysaa in dhululubadu ay aad uga dheer tahay dhexroorkeeda. Qaaciddadu waa:

$�=�\cdot �$

B=μ⋅M

Halkee:

• 
  $�$

  B waa xoogga goobta birlabta ee ku taal meel ka baxsan dhululubada (teslas, T).

• 
  $�$

  μ waa marin-u-helidda walaxda (joogto ah, badanaa
  $�0$

  μ0​ faakuumka ama hawada, oo la mid ah
  $4\times 10-7$

  4π×10−7 T m/A).

• 
  $�$

  M waa birlabeynta dhululubada (daqiiqad birlab ah halkii mug ee cutubka, A/m).

M waxaa loo xisaabin karaa sidan:

$�=�wadarta�dhululubo$

M=Vsilloondi​Wadarta​

Halkee:

• 
  $�wadarta$

  Mtotal​ waa wadarta guud ee daqiiqadda birlabta ee dhululubada (A m²).

• 
  $�dhululubo$

  Vsilloondu​ waa mugga dhululubada (m³).

Maskaxda ku hay in tani ay tahay xaalad la fududeeyay oo laga yaabo inaysan si sax ah u matalin qaybinta goobta birlabta kiisaska aadka u adag. Haddii birlabku aanu isku mid ahayn, ama haddii cabbirrada dhululubada aysan si weyn uga weynayn dhexroorkeeda, xisaabintu waxay noqonaysaa mid aad u adag waxayna u baahan kartaa farsamooyin tiro ama falanqayn ah.

Si aad u hesho natiijooyin sax ah, waxaa laga yaabaa inaad u baahato inaad isticmaasho habab horumarsan sida jilitaanka tirooyinka iyadoo la adeegsanayo falanqaynta walxaha xaddidan ama hababka falanqaynta ee tixgelinaya sifooyinka birlabta ee walaxda iyo qaybinta birlabta dhabta ah ee ku jirta silinda.

Odhaahda ah in goobta birlabta ay eber tahay gudaha dhululubo waxay noqon kartaa isfaham la'aan ama fududeyn xad dhaaf ah. Guud ahaan, goobta birlabta ee ku jirta dhululubo birlabta oo si siman u birlabta ah ma aha eber. Si kastaba ha ahaatee, iyadoo ku xiran xaaladaha gaarka ah iyo mala-awaalka, waxaa jira xaalado halkaas oo goobta birlabta ee ku jirta dhululubo ay noqon karto mid daciif ah ama ay muujin karto sifooyin gaar ah oo ka dhigi kara inay u muuqato in goobtu ay tahay mid aan la dafiri karin.

Waa kuwan dhowr xaaladood oo horseedi kara aragtida ah in goobta birlabtu ay eber tahay gudaha dhululubo:

1. Gaashaansho
2. Magnetization Midaysan

Waa muhiim in la ogaado in goobta birlabta ee ku jirta birlabta dhululubada ah ay ku xirnaan doonto arrimo kala duwan, oo ay ku jiraan qaybinta birlabta, qaabka birlabta, sifooyinka agabka, iyo saameynta dibadda sida goobaha birlabta ee u dhow ama gaashaanka. Guud ahaan, xoogga goobta birlabta waa la xisaabin karaa oo lagu matali karaa iyadoo lagu saleynayo arrimahan, laakiin goobtu uma badna inay si sax ah eber ugu noqoto gudaha dhululubo birlabta ah oo siman.

Haa, waxaa jiri kara goob birlabeed gudaha dhululubo godan, iyadoo la raacayo in dhululubo uu leeyahay nooc birlabeed ah. Joogitaanka iyo astaamaha goobta birlabeed ee gudaha dhululubo godan waxay ku xiran yihiin arrimo ay ka mid yihiin qaabka birlabeed, sifooyinka agabka, iyo joomatari ee dhululubo.

Goobta birlabta ee gudaha iyo dibadda birlabta dhululubada ah waxay ku xiran tahay arrimo kala duwan, oo ay ku jiraan qaabka birlabta, sifooyinka agabka, iyo joomatari ee dhululubada. Aan tixgelinno dhowr xaaladood:

1. Silsilad Magnetized ah oo Si Isku Mid ah loo Isticmaalay
2. Silsilad birlabaysan oo shucaac leh
3. Dhululubo Maqsin ah oo La Baabi'iyay
4. Silsiladda Gaashaandhigga Birlabta ah

Kuwani waa sharraxaado la fududeeyay, dhaqanka dhabta ah ee goobta birlabtana wuxuu noqon karaa mid aad u adag iyadoo ku xiran xaaladaha gaarka ah iyo mala-awaalka. Dhab ahaantii, qaybinta goobta birlabta waxaa badanaa lagu falanqeeyaa iyadoo la adeegsanayo qaabab xisaabeed ama software jilitaan ah oo tixgelinaya astaamaha faahfaahsan ee birlabta iyo deegaankeeda.
