Galibin abubuwan da ake amfani da su na maganadisu marasa ƙarfi ne masu ɗumbin ɗumbin ɗumbin yawa kuma suna da ƙarancin ƙarfi, yayin da kayan da ba su da ƙarfi kamar iska, jan ƙarfe, da takarda suna da tsari iri ɗaya.Wasu kayan, irin su baƙin ƙarfe, nickel, cobalt da alluran su, suna da ƙarfin ƙarfi.

Domin inganta halayen maganadisu na iskar-core coil, an gabatar da abin da ake kira Magnetic core, kamar yadda aka nuna a hoto 1.2.Fa'idar gabatar da ma'aunin maganadisu shine cewa baya ga babban karfinsa, tsayin hanyarsa na maganadisu (MPL-magnetic path length) a bayyane yake a kallo.Sai dai inda Z ke kusa da nada, maɗaukakiyar maganadisu galibi tana iyakance ga ainihin.

Kafin a cika ma'aunin maganadisu kuma wani ɓangaren coil ɗin ya dawo cikin ƙasa mara kyau, akwai wurin yankewa nawa ƙarfin maganadisu zai iya bayyana a cikin bayanan maganadisu.

Magnetomotive ƙarfi, Magnetic filin ƙarfi da magnetoresistance

MMF da ƙarfin filin maganadisu H sune mahimman ra'ayoyi guda biyu a cikin maganadisu.Suna da alaƙa mai lalacewa: MMF=NI, N shine adadin jujjuyawar coil, kuma ni ne na yanzu.

Ƙarfin filin Magnetic H, wanda aka ayyana azaman ƙarfin maganadisu kowane tsayin raka'a: H= MMF/MPL

Girman juzu'in Magnetic B, wanda aka ayyana azaman adadin layukan maganadisu a kowane yanki na yanki: B = φ/Ae

Juyin da MMF ke samarwa a cikin bayanan da aka bayar ya dogara da juriyar bayanan zuwa juriya.Wannan juriya ana kiransa magnetoresistance Rm

Dangantakar da ke tsakanin MMF, motsin maganadisu da juriya na maganadisu yayi kama da alakar da ke tsakanin karfin lantarki, halin yanzu da juriya.

Tazarar iska

Lokacin da aka ba da tsayin hanyar Magnetic MPL da ainihin yanki na giciye Ae, ɗigon maganadisu wanda ya ƙunshi manyan bayanan haɓaka yana da ƙarancin juriya na maganadisu.Idan da'irar maganadisu ta ƙunshi tazarar iska, ƙarfin maganadisu ya bambanta da na magnetic core da aka yi da ƙananan bayanai (kamar ƙarfe).Kusan duk rashin son wannan tafarki zai kasance a cikin tazarar iska, saboda rashin son tazarar iskar ya fi na bayanan maganadisu yawa.A aikace-aikace masu amfani, ana sarrafa juriyar maganadisu ta hanyar sarrafa girman ratar iska.
