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."

B) meel ka baxsan dhululubo magnetized isku mid ah oo ay la socdaan dhidibka dhexe waxaa lagu qiyaasi karaa iyadoo la isticmaalayo qaaciidada beerta gudaha solenoid ah. Qiyaastani waxay u malaynaysaa in dhululubada uu aad uga dheer yahay dhexroorkiisa. Habkani waa:

$�=�\cdot �$

B=μ⋅M

Halkee:

• 
  $�$

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

Halkee:

• 
  $�wadarta$

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

  Vcylinder waa mugga dhululubada (m³).

Maskaxda ku hay in tani ay tahay xaalad la fududeeyay lagana yaabo in aanay si sax ah u matalin qaybinta goobta magnetic ee kiisas aad u adag. Haddii magnetization-ku aanu labis ahayn, ama haddii cabbirrada dhululubada aanay si weyn uga weynayn dhexroorkeeda, xisaabintu waxay noqonaysaa mid aad u adag oo waxay u baahan kartaa farsamooyin tiro ama gorfayn.

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 goobta ay tahay mid aan la dafiri karin.

Waa kuwan dhowr xaaladood oo horseedi kara in la dareemo in goobta magnetic-ku uu eber yahay gudaha dhululubada:

1. Gaashaansho
2. Magnetization Midaysan

Waxaa muhiim ah in la ogaado in goobta magnetic ee gudaha magnet cylindrical ay ku xirnaan doonto arrimo kala duwan, oo ay ku jiraan qaybinta magnetization, qaabka magnetka, sifooyinka alaabta, iyo saameynta dibadda sida goobaha magnetic ama gaashaanka. Guud ahaan, xoogga goobta magnetic waa la xisaabin karaa oo la ekaan karaa iyada oo lagu salaynayo arrimahan, laakiin beerta uma badna in ay eber si sax ah u noqoto gudaha dhululubada magnetized isku midka ah.

Haa, waxaa jiri kara dhul birlab ah oo ku dhex jira dhululubo godan, waase haddii uu dhululubada leeyahay nooc ka mid ah magnetization. Joogitaanka iyo sifooyinka magnetic field gudaha dhululubada godan waxay ku xiran yihiin arrimo ay ka mid yihiin qaabka magnetization, sifooyinka alaabta, iyo joomatari dhululubada.

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. Silinder Radially Magnetized
3. Dhululubo Maqsin ah oo La Baabi'iyay
4. Silsiladda Gaashaandhigga Birlabta ah

Kuwani waa sharraxaadyo la fududeeyay, iyo dhaqanka dhabta ah ee goobta magnetic wuxuu noqon karaa mid aad u adag iyadoo ku xiran xaaladaha gaarka ah iyo fikradaha. Ficil ahaan, qaybinta magnetic field inta badan waxaa lagu falanqeeyaa iyadoo la isticmaalayo moodooyinka xisaabta ama software jilitaanka taas oo tixgalinaysa sifooyinka faahfaahsan ee magnetka iyo deegaankiisa.
