Core

Zvizhinji zvemagineti core zvinhu hazvina kunaka maconductor ekuyerera uye ane yakaderera permeability, nepo zvisiri-conductive zvinhu zvakaita semhepo, mhangura, uye bepa zvine kurongeka kwakafanana kwehukuru hwekupinda.Zvimwe zvinhu, zvakadai sesimbi, nickel, cobalt uye alloys avo, ane high permeability.

Kuti uvandudze magineti eiyo air-core coil, iyo magineti core inounzwa, sezvakaratidzwa mumufananidzo 1.2.Chakanakira kuunza magineti musimboti ndechekuti mukuwedzera kune yakakwirira permeability, yayo magineti nzira kureba (MPL-magineti nzira kureba) inojeka pakungotarisa.Kunze kwekunge Z iri padyo necoil, iyo magineti flux inonyanya kuvharirwa kupakati.

Pamberi pemagineti musimboti wazadzwa uye chikamu checoil chadzokera kune hollow state, pane yakachekwa-nzvimbo yekuti ingani magineti flux inogona kuoneka mune magineti data.

Magnetomotive simba, magnetic field simba uye magnetoresistance

MMF uye simba remagineti H ndiwo maviri akakosha pfungwa mune magineti.Vane hukama hwechikonzero: MMF=NI, N ndiyo nhamba yekutendeuka kwekoiri, uye ini ndiri ikozvino.

Magnetic field intensity H, iyo inotsanangurwa sesimba remagineti pahurefu hweyuniti: H = MMF / MPL

Magnetic flux density B, inotsanangurwa sehuwandu hwemitsara yemagineti panzvimbo yeyuniti: B = φ/Ae

Iyo flux inogadzirwa neMMF mune yakapihwa data zvinoenderana nekupokana kweiyo data kuyerera.Kupikisa uku kunonzi magnetoresistance Rm

Hukama huri pakati peMMF, magineti flux uye magineti kuramba hwakafanana nehukama pakati pesimba remagetsi, razvino uye kuramba.

Mhepo gap

Kana iyo magineti nzira kureba MPL uye yepakati-chikamu-chikamu nzvimbo Ae yakapihwa, iyo magineti musimboti inoumbwa nepamusoro permeability data ine yakaderera magineti kuramba.Kana iyo magineti yedunhu iine gap remhepo, kurwisa kwayo magineti kwakasiyana neiyo yemagineti core yakagadzirwa neakaderera resistivity data (senge iron).Kunenge kusada kwese kweiyi nzira kuchava mugomba remhepo, nekuti kusada kwegomba remhepo kwakakura kupfuura iyo data remagineti.Mumashandisirwo anoshanda, iyo magineti kuramba inodzorwa nekudzora saizi yegeji remhepo.

Yakaenzana permeability

Mhepo gap kusada ndeye Rg, kureba kwegomba remhepo iLG, uye kusada kwepakati ndeye Rmt.

Kugamuchirwa kubvunza BIG kune magineti musimboti kurongeka.Tine vashandi vebasa rehunyanzvi kuti vakupe iwe neruzivo rwakadzama.
