Sidee loo cabbiraa Xoogga Birlabta?

Birlabku wuxuu ahaa walxo xiiso leh qarniyo badan, isagoo soo jiitay saynisyahannada iyo kuwa xiiseeya awooddooda qarsoon ee soo jiidashada agabyada qaarkood. Laga bilaabo irbadaha kombaska ee hagaya sahamiyeyaasha hore ilaa farsamooyinka adag ee tignoolajiyada casriga ah, birlabku wuxuu door muhiim ah ka ciyaaraa dhinacyo kala duwan oo nolosheenna ah. Laakiin sidee baan u cabbirnaa xoogga kuwangoobaha birlabtaSideen u cabbirnaa awoodda birlabta? Aan u fiirsanno hababka iyo qalabka loo isticmaalo in lagu cabbiro xoogga birlabta.

Xoogga Goobta Birlabta

Xoogga birlabku waxaa aasaas ahaan lagu go'aamiyaa goobtiisa birlabeed, aagga ku wareegsan birlabku halkaas oo saameyntiisa laga dareemo. Goobtan waxaa lagu matalaa khadadka xoogga, oo ka bilaabma cidhifka waqooyi ee birlabku ilaa cidhifka koonfureed. Inta badan cufnaanta xariiqyadan, ayaa xoogaysata goobta birlabku.

Gauss iyo Tesla: Cutubyada Cabbirka

Si loo qiyaaso xoogga goobta birlabta, saynisyahannadu waxay isticmaalaan laba cutub oo cabbir aasaasi ah: Gauss iyo Tesla.

Gauss (G): Waxaa loogu magac daray xisaabiyaha iyo fiisigiska Jarmalka Carl Friedrich Gauss, cutubkani wuxuu cabbiraa cufnaanta qulqulka magnetic-ka ama kicinta magnetic-ka. Hal Gauss wuxuu la mid yahay hal Maxwell sentimitir laba jibbaaran. Si kastaba ha ahaatee, sababtoo ah cabbirka yar ee Gauss, gaar ahaan xaaladaha casriga ah, saynisyahannadu waxay inta badan u isticmaalaan Tesla goobaha magnetic-ka ee xooggan.

Tesla (T): Waxaa loogu magac daray hal-abuure reer Serbian-American ah iyo injineer koronto Nikola Tesla, cutubkani wuxuu matalaa cufnaan birlabeed oo weyn marka loo eego Gauss. Hal Tesla wuxuu la mid yahay 10,000 Gauss, taasoo ka dhigaysa cutub wax ku ool ah oo lagu cabbiro goobaha birlabeed ee xooggan, sida kuwa ay soo saaraan birlabyada awoodda badan ee loo isticmaalo cilmi-baarista sayniska ama codsiyada warshadaha.

Magnetometers-ka

Magnetometers-ku waa qalab loogu talagalay in lagu cabbiro xoogga iyo jihada goobaha birlabta. Qalabkani wuxuu ku yimaadaa qaabab kala duwan, laga bilaabo kombasyada gacanta lagu qaato ee fudud ilaa qalabka shaybaarka ee casriga ah. Waa kuwan noocyada caadiga ah ee magnetometers-ka loo isticmaalo cabbiraadda xoogga goobta birlabta:

1. Qalabka cabbira Fluxgate: Mitirayaashan magnetometer-ka waxay adeegsadaan mabaadi'da kicinta elektromagnetic-ka si ay u cabbiraan isbeddellada ku yimaada goobaha birlabta. Waxay ka kooban yihiin hal ama in ka badan xudunta birlabta oo ay ku wareegsan yihiin gariirado silig ah. Marka ay la kulmaan goob birlabta ah, xudunta ayaa noqda birlabta, taasoo keenta calaamad koronto oo ku jirta gariiradaha, taas oo la cabbiri karo oo la hagaajin karo si loo go'aamiyo xoogga goobta birlabta.

2. Magnetometers-ka Saamaynta Hoolka: Cabbiraadaha magnetometer-ka ee saamaynta hoolka waxay ku tiirsan yihiin saamaynta Hall-ka, kaas oo qeexaya soo saarista farqiga danabka (danabka Hall-ka) ee dhex mara kontaroolaha korontada marka lagu hayo goob birlab ah oo ku toosan socodka hadda socda. Iyadoo la cabbirayo danabkan, magnetometer-yada saamaynta Hall-ka waxay go'aamin karaan xoogga goobta birlabka.

3. Qalabka cabbira mitirrada SQUID: Qalabka Magnetometer-ka ee Superconducting Quantum Interference Device (SQUID) ayaa ka mid ah magnetometer-yada ugu xasaasiga badan ee la heli karo. Waxay ku shaqeeyaan iyadoo lagu saleynayo sifooyinka quantum ee superconductors-ka, taasoo u oggolaanaysa inay ogaadaan goobaha magnetka ee aadka u daciifka ah, ilaa heerka femtoteslas (10^-15 Tesla).

Kala-hagaajinta iyo Jaangooynta

Si loo hubiyo cabbiraadaha saxda ah, cabbiraadaha magnetometer-ka waa in si habboon loo hagaajiyaa oo loo habeeyaa. Kala-hagaajintu waxay ku lug leedahay isbarbardhigga wax soo saarka magnetometer-ka iyo awoodaha goobta magnetka ee la yaqaan si loo dhiso xiriir toosan oo u dhexeeya akhrinta qalabka iyo qiimayaasha goobta magnetka ee dhabta ah. Kala-hagaajintu waxay hubineysaa in cabbiraadaha lagu qaado magnetometer-yada kala duwan ay yihiin kuwo isku mid ah oo la barbar dhigi karo.

Adeegsiga Magnetometry

Awoodda lagu cabbiro xoogga goobta birlabta si sax ah waxay leedahay codsiyo badan oo ku baahsan qaybaha kala duwan:

Juqraafi ahaanMagnetometers-ka waxaa loo isticmaalaa in lagu barto goobta birlabta ee Dhulka, taasoo bixisa macluumaad qiimo leh oo ku saabsan qaab-dhismeedka iyo halabuurka gudaha meeraha.

Hagaajinta: Kombaasta, oo ah nooc ka mid ah magnetometer-ka, ayaa ahaa qalab muhiim u ah hagista tan iyo waagii hore, iyagoo ka caawinaya badmaaxiinta iyo sahamiyayaasha inay helaan jidkooda iyagoo maraya badweynta ballaaran.

Sayniska AgabkaMagnetometry: Magnetometry waxaa loo isticmaalaa in lagu gartowalxaha birlabta ahiyo inay bartaan sifooyinkooda, kuwaas oo muhiim u ah horumarinta teknoolojiyada sida aaladaha kaydinta birlabta iyo mashiinnada sawir-qaadista ra'yi-celinta magnetic (MRI).

Sahaminta Hawada SareMagnetometers-ka waxaa lagu rakibay dayax-gacmeedka si ay u bartaan goobaha birlabta ee jirka cirka, iyagoo bixinaya aragtiyo ku saabsan hal-abuurkooda iyo taariikhdooda juqraafiyeed.

Gunaanad

Cabbirka xoogga goobta birlabta ayaa lagama maarmaan u ah fahamka dhaqanka birlabta iyo adeegsigooda goobaha kala duwan. Iyada oo loo marayo cutubyo sida Gauss iyo Tesla iyo aaladaha sida magnetometers, saynisyahannadu waxay si sax ah u cabbiri karaan xoogga goobaha birlabta, iyagoo u gogol xaaraya horumarka tignoolajiyada, sahaminta, iyo cilmi-baarista sayniska. Marka fahamkeenna birlabta uu sii socdo, sidoo kale awooddeenna aan u adeegsanno awooddeeda faa'iidada aadanaha.
