Undoqo

Uninzi lwezixhobo ezingundoqo zemagneti ziziqhubi ezihlwempuzekileyo zokuguquguquka kwaye zinokungena kancinci, ngelixa izinto ezingaqhubekiyo ezifana nomoya, ubhedu, kunye nephepha zinomyalelo ofanayo wobungakanani bokungena.Ezinye izinto, ezifana nentsimbi, i-nickel, i-cobalt kunye ne-alloys yazo, zinokungena okuphezulu.

Ukuze kuphuculwe iimpawu zamagnetic ze-coil-core coil, i-core magnetic ifakwe, njengoko kuboniswe kuMzobo 1.2.Inzuzo yokwazisa i-core magnetic kukuba ukongeza kwi-permeability yayo ephezulu, ubude bayo bendlela yamagnetic (ubude bendlela ye-MPL-magnetic) icacile ngokujonga.Ngaphandle kwalapho u-Z ekufutshane nekhoyili, i-magnetic flux ivalelwa ikakhulu kumbindi.

Ngaphambi kokuba i-core magnetic igcwaliswe kwaye inxalenye yekhoyili ibuyela kwimeko engenanto, kukho indawo yokusika ukuba ingakanani i-flux yamagnetic enokuthi ibonakale kwidatha yemagnethi.

Amandla emagnethi, amandla emagnethi kunye nokumelana nemagnethi

I-MMF kunye namandla ommandla wemagnethi H ziikhonsepthi ezimbini ezibalulekileyo kwimagnetism.Banobudlelwane be-causal: MMF=NI, N linani lokujika kwekhoyili, kwaye mna ndingulo ngoku.

Ubukhulu bendawo yemagnethi H, echazwa njengamandla emagnethi ngobude beyunithi: H= MMF /MPL

Uxinaniso lwemagnethi oluguquguqukayo B, luchazwa njengenani lemigca yomhlaba wemagnethi kwindawo nganye yeyunithi: B = φ/Ae

I-flux eyenziwa yi-MMF kwidatha enikiweyo ixhomekeke ekuchaseni idatha ukuba ihambe.Oku kuxhathisa kubizwa ngokuba yi-magnetoresistance Rm

Ubudlelwane phakathi kwe-MMF, i-magnetic flux kunye nokumelana nemagnethi kufana nobudlelwane phakathi kwamandla e-electromotive, okwangoku kunye nokumelana.

Umsantsa womoya

Xa ubude bendlela yemagnethi ye-MPL kunye ne-core cross-sectional area Ae inikezelwa, i-magnetic core ehlanganiswe nedatha ephezulu yokungena inokumelana nemagnethi ephantsi.Ukuba i-magnetic circuit iqulethe i-gap yomoya, ukuxhathisa kwayo kwamagnetic kuyahluke kulowo we-magnetic core eyenziwe ngedatha ephantsi yokumelana (njengentsimbi).Phantse konke ukungafuni kwale ndlela kuya kuba kwi-gap yomoya, kuba ukungafuni kwe-gap yomoya kukhulu kakhulu kunedatha yamagnetic.Kwizicelo ezisebenzayo, ukuxhathisa kwamagnetic kulawulwa ngokulawula ubungakanani besithuba somoya.

Ukungena ngokulinganayo

Ukuthandabuza kwe-gap yomoya yi-Rg, ubude be-gap yomoya yi-LG, kwaye ukungafuni okungundoqo okupheleleyo yi-Rmt.

Wamkelekile ukudibana ne-BIG ukuze ufumane undoqo wokuodola.Sinabasebenzi benkonzo abaqeqeshiweyo ukukubonelela ngeenkonzo ezineenkcukacha.
