Habka shaqada

1) Saamaynta Magnetoelectric

Marka loo eego sharciga Faraday ee soo saarista elektromagnetic-ka, baaxadda xoogga koronto-dhaliyaha ee ka dhasha gariiradda waxay ku xiran tahay isbeddelka heerka isbeddelka qulqulka magnetka ee dhex mara gariiradda marka uu N-turnaanta u wareego goobta magnetic oo uu gooyo xariiqda xoogga birlabeedka ( ama isbeddelka qulqulka magnetic ee goobta magnetic meesha gariiraddu ku taal).

Dareemaha magnetoelectric dhaqaaqa toosan

Dareemka magnetoelectric ee toosan ee dhaqaaqa wuxuu ka kooban yahay magnet joogto ah, gariirad iyo guri dareemaha.

Marka qolofku uu gariiro jidhka gariiraya si loo cabbiro oo inta jeer ee gariirku aad uga sarreeyo inta jeer ee dabiiciga ah ee dareemayaasha, sababtoo ah gu'gu waa jilicsan yahay oo cufnaanta qaybta dhaqdhaqaaqa waa mid aad u weyn, aad bay u daahday qaybta dhaqdhaqaaqa. si aad u gariirto (is taagto) jidhka gariiraya.Waqtigan xaadirka ah, xawaaraha dhaqdhaqaaqa ee u dhexeeya magnetka iyo gariiradda wuxuu ku dhow yahay xawaaraha gariirka ee gariiriyaha.

Nooca wareega

Bir jilicsan, gariirad iyo magnet joogto ah ayaa go'an.Qalabka cabbiraadda ee ka samaysan walxaha birlabeedka ayaa lagu rakibay jidhka wareega ee la qiyaasay.Mar kasta oo iliggu wareego, iska caabbinta magnetka ee wareegga magnetka ee ka sameysan inta u dhexeysa qalabka cabbirka iyo birta jilicsan ayaa hal mar isbedesha, qulqulka magnetic wuxuu sidoo kale isbeddelaa hal mar.Inta jeer ee (tirada garaaca wadnaha) ee xoogga koronto-dhaliyaha ee gariiradda ayaa la mid ah sheyga tirada ilkaha ee qalabka cabbirka iyo xawaaraha wareega.

Saamaynta hoolka

Marka semiconductor ama bir bir ah lagu dhejiyo goob birlab ah, marka hadda (jihada diyaaradeed ee foil-ku toosan goobta magnetic) ay u socoto, xoogga elektiroonigga ah ayaa loo soo saaraa jihada siman ee magnetic field iyo hadda.Dhacdadan waxa loo yaqaan Hall effect.

element Hall

Qalabka Hoolka ee inta badan loo isticmaalo waa germanium (Ge), Silicon (Si), indium antimonide (InSb), indium arsenide (InAs) iyo wixii la mid ah.N-nooca germanium waa sahlan tahay in la soo saaro oo wuxuu leeyahay isku-dhafka Hall-ka wanaagsan, waxqabadka heerkulka iyo toosnaanta.Silicon nooca P-ga ah ayaa leh khadka ugu fiican, isku-dheelitirnaantiisa Hall iyo waxqabadka heerkulku waxay la mid yihiin kuwa N-nooca germanium, laakiin dhaqdhaqaaqa elektarooniga ah waa hooseeyaa awoodda wax qabadkeeduna waa liidataa, sidaa darteed inta badan looma isticmaalo sidii hal Hall oo keliya. curiye.
