Uyini umehluko phakathi kwesekethe kazibuthe kazibuthe oqinile kanye nezici ezibonakalayo zesekethe?

Umehluko omkhulu phakathi kwezakhiwo ezibonakalayo zamasekethe kazibuthe namasekhethi kagesi umi kanje:
(1) Kukhona izinto ezinhle zokuqhuba ngokwemvelo, futhi kukhona nezinto ezivikela amandla kumanje. Isibonelo, ukumelana kwethusi kungu-1.69 × 10-2Qmm2/m, kuyilapho ukumelana nenjoloba cishe kuphindwe izikhathi ezingu-10. Kodwa kuze kube manje, azikho izinto ezivikelwe ngokumelene ne-magnetic flux ezitholakele. Ukungena kukazibuthe kwe-bismuth, okunozibuthe okuncane kakhulu okufinyeleleka, kungu-0. 99982μ. Ukungena komoya kazibuthe ngu-1. 000038μ. Ngakho-ke umoya ungabonakala njengento enokungena okuphansi kazibuthe. Ukufinyeleleka okuhlobene kwezinto ze-ferromagnetic ezinokungeneka okungcono kakhulu kumayelana namandla esithupha ayi-10.

(2)Okwamanje ukugeleza kwenqwaba ekhokhisiwe kukhondakta. Ngenxa yokuba khona kokumelana ne-conductor, amandla e-electrodynamic asebenza kunqwaba ekhokhisiwe futhi asebenzise amandla, futhi ukulahlekelwa kwamandla kuguqulwa kube ukushisa. I-flux kazibuthe ayimele ukunyakaza kwanoma iyiphi insa, futhi ayimeli ukulahleka kwamandla, ngakho-ke lesi sifaniso siyakhohlisa. Isekhethi kanye nesekhethi kazibuthe zibonakala zihlukene, futhi ngayinye inento yayo engangabazeki yokuqabula ukucabanga ngaphakathi kwenqwaba. Lesi sifaniso sikhubazekile ngenxa yokuphelelwa amandla. Isifunda kanye nesekhethi kazibuthe kubonakala kuhlukile, futhi ngayinye inencazelo yayo yomzimba engabuzwanga.

Umjikelezo kazibuthe ukhululekile:

(1) Akukho ukuphumula kumjikelezo kazibuthe njengakusekhethi; i-flux kazibuthe ikhona yonke indawo.

(3) Iziyingi kazibuthe cishe azinamugqa. I-ferromagnetic substance magnetoresistance is nonlinear, i-air gap magnetoresistance is linear. Umthetho we-ohm nesililo sokungabaza sokujikeleza kazibuthe okubalwe ngenhla kulungile kuphela kububanzi bomugqa. Ngakho umklamo wangempela, ngokuvamile usebenzisa ijika le-BH ukuze uthole indawo yokusebenza.

(2) Njengoba ingekho into engangeneki ngokuphelele, i-flux kazibuthe ayivimbeli, ingxenye kuphela ye-flux idlula eduze kwesekethe kazibuthe enqunyiwe, futhi enye ihlakazeke endaweni ezungeze isekethe, ebizwa ngokuthi ukuvuza, futhi ukubala okunembile kanye nesilinganiso salokhu kuvuza kunzima, kodwa akunakuzitshwa.
