Silinder Neodymium Magnet 6*13mm - Muunad Bilaash Ah Oo La Heli Karo | Fullzen

Xisaabinta goobta magnetic (
$�$

B) agagaarka magnet cylindrical waxay noqon kartaa mid aad u adag, taas oo ku xidhan qaybinta magnetization gudaha dhululubada. Halkan, waxaan ku tilmaami doonaa kiis la fududeeyay halkaas oo aan ku haysano dhululubo isku mid ah oo magnetized ah oo leh dhidibka magnetization oo la siman dhidibka dhululubada. Tan waxaa badanaa lagu tilmaamaa "silinda dherer ahaan magnetized."

Dhulka magnetic (
$�$

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 magnetic meel ka baxsan dhululubada (in teslas, T).

• 
  $�$

  μ waa qulqulka walxaha (joogto ah, badanaa
  $�0$

  μ0 vacuum ama hawo, oo le'eg
  $4�\times 10-7$

  4π×10-7 T m/A).

• 
  $�$

  M waa magnetization ee dhululubada (daqiiqado magnetic halkii mugga, gudaha A/m).

Dhululubo magnetized isku mid ah,
$�$

M waxaa loo xisaabin karaa sida:

$�=�\; wadarta$

M=VcylinderMtotal

Halkee:

• 
  $guud\; ahaan$

  Mtotal waa wadarta guud ee daqiiqada magnetic ee dhululubada (ku jira A m²).

• 
  $�\; dhululubo$

  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 loo helo natiijooyin sax ah oo dheeraad ah, waxaa laga yaabaa inaad u baahato inaad isticmaasho habab horumarsan sida jilitaanka nambarada adigoo isticmaalaya falanqaynta element dhamaadka ama habab lafo-gureedka kuwaas oo tixgelinaya sifooyinka magnetic ee walxaha iyo qaybinta magnetization dhabta ah ee gudaha dhululubada.

Hadalka ah in goobta birlabku ay eber tahay gudaha dhululubada waxay noqon kartaa isfaham la'aan ama fududayn. Guud ahaan, goobta birlabeedka gudaha dhululubo magnetized isku mid ah maaha eber. Si kastaba ha ahaatee, iyadoo ku xiran xaaladaha gaarka ah iyo malo-awaalka, waxaa jira kiisas goobta magnetic gudaha dhululubada ay noqon karto mid daciif ah ama soo bandhigto waxyaabo gaar ah oo laga yaabo inay u ekaato in garoonku yahay mid la dayacay.

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

1. gaashaanka
2. Magnetization lebbisan

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.

Meesha birlabeedka gudaha iyo dibadda ee magnet cylindrical waxay ku xiran tahay arrimo kala duwan, oo ay ku jiraan qaabka magnetization, sifooyinka alaabta, iyo joomatari ee dhululubada. Aynu tixgelinno dhowr xaaladood:

1. Silinder Si La Mid Ah Looga Magnetized
2. Silinder Radially Magnetized
3. Silinder Godan
4. Silinder gaashaanka magnetic

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.
