Ingqikithi

Iningi lezinto eziwumgogodla kazibuthe zingamakhondaktha ampofu wokuguquguquka futhi zinokungena okuphansi, kuyilapho izinto ezingaphenduki njengomoya, ithusi, nephepha zinokuhleleka okufanayo kobukhulu bokungena. Ezinye izinto, njengensimbi, i-nickel, i-cobalt nama-alloys azo, zinokungena okuphezulu.

Ukuze kuthuthukiswe izici kazibuthe zekhoyili ye-air-core, i-core magnetic yethulwa, njengoba kuboniswe kuMfanekiso 1.2. Inzuzo yokwethula indikimba kazibuthe ukuthi ngaphezu kokungena kwayo okuphezulu, ubude bayo bendlela kazibuthe (ubude bendlela ye-MPL-magnetic) bucacile ngokubuka nje. Ngaphandle kwalapho u-Z eseduze khona nekhoyili, i-flux kazibuthe ivaleleke kumongo.

Ngaphambi kokuthi ingqikithi kazibuthe igcwaliswe futhi ingxenye yekhoyili ibuyele endaweni engenalutho, kunephuzu lokunqamula lokuthi ingakanani i-flux kazibuthe engavela kudatha kazibuthe.

Amandla kazibuthe, amandla kazibuthe kanye nokumelana ne-magnetoresistance

I-MMF namandla kazibuthe H yimibono emibili ebalulekile kukazibuthe. Banobudlelwano obuyimbangela: MMF=NI, N inombolo yokuphenduka kwekhoyili, mina ngingumsinga.

Amandla kazibuthe ku-H, achazwa njengamandla kazibuthe ngobude beyunithi ngayinye: H= MMF/MPL

Ubuningi be-Magnetic flux B, echazwa njengenani lemigqa yensimu kazibuthe endaweni yeyunithi ngayinye: B = φ/Ae

Ukuguquguquka okukhiqizwa yi-MMF kudatha ethile kuncike ekuphikisweni kwedatha ukuze iguqe. Lokhu kumelana kubizwa nge-magnetoresistance Rm

Ubudlelwano phakathi kwe-MMF, i-magnetic flux kanye nokumelana kazibuthe bufana nobudlelwano phakathi kwamandla e-electromotive, amanje kanye nokumelana.

Igebe lomoya

Uma ubude bendlela kazibuthe i-MPL kanye nendawo ephakathi nendawo eyi-Ae kunikezwa, ingqikithi kazibuthe eyakhiwe idatha ephezulu yokungena inokumelana nozibuthe okuphansi. Uma umjikelezo kazibuthe uqukethe igebe lomoya, ukumelana kwawo kukazibuthe kuhlukile kulokho komongo kazibuthe owenziwe ngedatha ephansi yokumelana (njengensimbi). Cishe konke ukungabaza kwale ndlela kuzoba kugebe lomoya, ngoba ukungabaza kwegebe lomoya kukhulu kakhulu kunokwedatha kazibuthe. Ezisetshenziswa ezingokoqobo, ukumelana kazibuthe kulawulwa ngokulawula usayizi wegebe lomoya.

Ukungena okulingana

Ukungabaza kwegebe lomoya ngu-Rg, ubude begebe lomoya yi-LG, futhi ukungabaza okuphelele okuyinhloko yi-Rmt.

Siyakwamukela ukuthi uthintane ne-BIG ukuze uthole ukuhleleka okuyinhloko kazibuthe. Sinezisebenzi zesevisi ezichwepheshile ukuze zikunikeze ngamasevisi anemininingwane.
