Ukulinganisa Iimpawu zeMagnet eziSigxina

Uvavanyo lweMagnet oluSisigxina: Imbono yoMchwephesha

Ukubaluleka Kokulinganisa Ngokuchanekileyo
Ukuba usebenza ngezinto zemagnethi, uyazi ukuba ukusebenza okuthembekileyo kuqala ngokulinganisa ngokuchanekileyo. Idatha esiyiqokelelayo kuvavanyo lwemagnethi ichaphazela ngokuthe ngqo izigqibo kubunjineli beemoto, izixhobo ze-elektroniki zabathengi, itekhnoloji yezonyango, kunye nokusetyenziswa kwamandla avuselelekayo.

Iiparameter ezine ezibalulekileyo zokusebenza
Xa sivavanya iimagnethi ezisisigxina kwilebhu, sihlala sijonga iiparameter ezine ezibalulekileyo ezichaza amandla azo:

Br: Inkumbulo kaMagnet
Ukubuyela umva (Br):Khawucinge oku njenge "memori" yemagnetism. Emva kokuba sisuse intsimi yemagnetizing yangaphandle, uBr usibonisa ukuba ingakanani i-magnetic egcina amandla ayo. Oku kusinika isiseko samandla emagnethi xa esetyenziswa ngokwenene.

I-Hc: Ukuchasana ne-Demagnetization
Ukunyanzela (Hc):Cinga ngale nto "njengomandla" emagnethi - amandla ayo okumelana nokususwa kwemagnethi. Siyicalula le nto ibe yi-Hcb, esixelela ukuba kufuneka i-reverse field ukuze kurhoxiswe i-magnetic output, kunye ne-Hci, etyhila ukuba kufuneka i-field enamandla kangakanani ukuze kucinywe ngokupheleleyo ulungelelwaniso lwangaphakathi lwemagnethi.

I-BHmax: Isalathisi samandla
Imveliso yamandla aphezulu (i-BHmax):Eli linani eligcwele amandla esilikhupha kwi-hysteresis loop. Limele uxinzelelo lwamandla oluphezulu olunokunikezelwa zizinto zemagnethi, nto leyo eyenza ukuba libe yindlela esiyisebenzisayo yokuthelekisa iintlobo ezahlukeneyo zemagnethi kunye namanqanaba okusebenza.

Hci: Uzinzo Phantsi koXinzelelo
Uxinzelelo lwangaphakathi (Hci):Kwiimagnethi zeNdFeB ezisebenza kakhulu namhlanje, le yindlela yokwenza okanye yokuyisusa. Xa amaxabiso e-Hci enamandla, imagnethi inokumelana neemeko ezinzima - kuquka amaqondo obushushu aphezulu kunye nemimandla yemagnethi echaseneyo - ngaphandle kokulahleka okukhulu kokusebenza.

Izixhobo zokulinganisa ezibalulekileyo
Enyanisweni, sixhomekeke kwizixhobo ezikhethekileyo ukuze sibambe ezi mpawu. I-hysteresisgraph isasebenza njengeyona nto siyenzayo elebhu, ichaza i-BH curve epheleleyo ngokusebenzisa imijikelo yemagnetization elawulwayo. Phantsi kwefektri, sihlala sitshintshela kwizisombululo eziphathwayo ezifana neHall-effect gaussmeters okanye iiHelmholtz coils ukuze siqinisekise umgangatho ngokukhawuleza.

Ukuvavanya iiMagnets ezine-Adhesive-Backed
Izinto ziba nzulu ngakumbi xa sivavanyaiimagnethi ze-neodymium ezixhaswa yi-glueUkulungela kweglue eyakhelwe ngaphakathi kuza neengxaki ezithile zovavanyo:

Imingeni yoMdlalo
Imingeni yokuFaka:Loo maleko unamathelayo uthetha ukuba imagnethi ayihlali kakuhle kwizixhobo zovavanyo eziqhelekileyo. Nezikhewu zomoya ezincinci zinokuphazamisa ukufunda kwethu, zifune izisombululo zobuchule zokufakela ngokufanelekileyo.

Izinto eziqwalaselwayo ngeJometri
Izinto eziqwalaselwayo kwiFomu:Ubume bazo obuncinci nobugobekayo bufuna ukulungiswa ngokwezifiso. Ukuseta okuqhelekileyo okwenzelwe iibhloko eziqinileyo akusebenzanga xa isampuli yakho yovavanyo inokuguquguquka okanye ingenabo ubukhulu obufanayo.

Iimfuno zoVavanyo lweNdawo
Iimfuneko zoKwahlukaniswa kweMagnetic:Njengazo zonke iimvavanyo zemagnethi, kufuneka sibe nomdla wokugcina yonke into engekho magnethi kufutshane. Nangona iglu ngokwayo ingathathi cala kwimagnethi, naziphi na izixhobo zentsimbi ezikufutshane okanye ezinye iimagnethi ziya kuphazamisa iziphumo zethu.

Kutheni Uvavanyo Lubalulekile？
Iingxaki zovavanyo oluchanekileyo ziphezulu. Nokuba singamamagnethi afanelekileyo kwiimoto zombane okanye izixhobo zokuxilonga zonyango, akukho ndawo yokwenza iimpazamo. Ngeentlobo ezixhaswa yi-adhesive, asijongi nje amandla e-magnetic - sikwaqinisekisa ukuqina kobushushu, kuba umaleko we-adhesive uhlala ungasebenzi ngaphambi kwe-magnet ngokwayo kwiimeko zobushushu obuphezulu.

Isiseko Sokuthembeka
Ekugqibeleni, uvavanyo olucokisekileyo lwemagnethi aluyonto nje yokujonga umgangatho - sisiseko sokusebenza okuqikelelweyo kuyo yonke into oyenzayo. Imigaqo ephambili ihlala ifana kuzo zonke iintlobo zemagnethi, kodwa iingcali ezikrelekrele ziyazi ukuba kufuneka zilungise nini iindlela zazo kwiimeko ezikhethekileyo ezifana noyilo oluncamathelayo.
