Ukulinganisa iimpawu zeMazibuthe eziSisigxina

Uvavanyo lweMagnet oluSigxina: Imbono yeGcisa

Ukubaluleka Komlinganiselo Ochanekileyo
Ukuba usebenza ngezixhobo zamagnetic, uyazi ukuba ukusebenza okuthembekileyo kuqala ngomlinganiselo ochanekileyo. Idatha esiyiqokelelayo kuvavanyo lwemagnethi inefuthe ngqo kwizigqibo zobunjineli beemoto, umbane wabathengi, ubuchwephesha bezonyango, kunye nosetyenziso lwamandla ahlaziyekayo.

Iiparamitha ezine zokuSebenza eziBalulekileyo
Xa sivavanya iimagnethi ezisisigxina elebhu, sihlala sijonga iiparamitha ezine ezibalulekileyo ezichaza amandla abo:

Br: Inkumbulo yeMagnet
Remanence (Br):Yiba nomfanekiso wemagnethi "inkumbulo" yemagnethi. Emva kokuba sisuse indawo yemagnethi yangaphandle, iBr isibonisa ukuba bungakanani ubungakanani bemagnethi obugcinayo. Oku kusinika isiseko samandla emagnethi kusetyenziso lokwenyani.

Hc: Ukuxhathisa kwi-Demagnetization
Ukunyanzeliswa (Hc):Cinga oku njenge "willpower" yemagnethi - ukukwazi kwayo ukuxhathisa i-demagnetization. Siyiqhekeza le nto ibe yi-Hcb, esixelela indawo ebuyela umva efunekayo ukurhoxisa ukuphuma kwemagnethi, kunye ne-Hci, ebonisa ukuba sidinga intsimi eyomeleleyo kangakanani ukucima ngokupheleleyo ulungelelwaniso lwangaphakathi lwemagnethi.

BHmax: Isalathisi saMandla
Ubuninzi beMveliso yaMandla (BHmax):Eli linani eligcwele amandla esilitsalayo kwi-hysteresis loop. Imele ugxininiso lwamandla oluphezulu olunokuhanjiswa yimagnethi, iyenza ibe yimetric yethu yokuthelekisa iintlobo ezahlukeneyo zemagnethi kunye namanqanaba okusebenza.

Hci: Uzinzo phantsi koxinzelelo
Unyanzeliso lwangaphakathi (Hci):Kwimagnethi yeNdFeB yanamhlanje esebenza kakhulu, oku kukwenza okanye ukuqhawula. Xa ixabiso le-Hci lomelele, imagnethi inokumelana neemeko ezinzima - kubandakanywa ubushushu obuphezulu kunye nokuchasana nommandla wemagnethi - ngaphandle kwelahleko ebalulekileyo yokusebenza.

Izixhobo zoMlinganiso eziBalulekileyo
Enyanisweni, sithembele kwizixhobo ezikhethekileyo ukubamba ezi zakhiwo. I-hysteresisgraph ihlala ilihashe lethu laselabhoratri, isenza imephu epheleleyo ye-BH ijika ngemijikelo yemagnetization elawulwayo. Kumgangatho wefektri, sihlala sitshintshela kwizisombululo eziphathwayo ezifana ne-Hall-effect gaussmeters okanye iikhoyili zeHelmholtz zokuqinisekisa umgangatho okhawulezayo.

Ukuvavanya i-Adhesive-Backed Magnets
Izinto ziba mandundu ngakumbi xa sivavanyaiimagnethi ze-neodymium ezincamathelayo. Ukulunga kokuncamathelisa okwakhelwe ngaphakathi kuza kunye neengxaki zovavanyo:

Imingeni yokuLungisa
Ukunyuka imingeni:Loo maleko incangathi ithetha ukuba umazibuthe akaze ahlale ngokugqibeleleyo kuvavanyo oluqhelekileyo. Kwanezikhewu zomoya ezincinci zinokugqwetha ukufunda kwethu, zifuna izisombululo zoyilo zokunyuswa ngokufanelekileyo.

Iingqwalasela zeJometri
Iingqwalasela zeFom Factor:Ubume babo obubhityileyo, obugobekileyo bufuna ukulungiswa ngokwesiko. Ukuseta okusemgangathweni okwenzelwe iibhloko eziqinileyo azisebenzi nje xa isampulu yakho yovavanyo inokuguquguquka okanye ingenabo ubunzima obufanayo.

IiMfuno zokuSingqongileyo zoVavanyo
IiMfuneko zokuzahlula ngeMagnetic:Njengalo lonke uvavanyo lwemagnethi, kufuneka sibe nenzondelelo yempambano ngokugcina yonke into engeyiyo imagnethi ikufutshane. Ngelixa i-adhesive ngokwayo ingathathi hlangothi ngokwemagnethi, naziphi na izixhobo zentsimbi ezikufutshane okanye ezinye iimagnethi ziya kuphazamisa iziphumo zethu.

Kutheni Kubalulekile Ukuvavanywa??
Uvavanyo oluchanekileyo luphezulu. Nokuba sifanelekile kwiimagnethi zokuqhuba isithuthi sombane okanye isixhobo soxilongo lwezonyango, akukho ndawo yempazamo. Ngeentlobo ezincamathelayo ezincamathelayo, asijongi nje amandla emagnethi- sikwaqinisekisa ukomelela kwe-thermal, kuba umaleko wokuncamathelisa uhlala usilela phambi kokuba umazibuthe ngokwawo kwiimeko zobushushu obuphezulu.

Isiseko sokuthembeka
Ekupheleni kosuku, uvavanyo olucokisekileyo lwemagnethi alukho nje ukujonga umgangatho - sisiseko sokusebenza okuqikelelweyo kuso sonke isicelo. Imigaqo engundoqo ihlala ifana kuzo zonke iintlobo zemagnethi, kodwa amagcisa akrelekrele ayazi ukuba angaziqhelanisa nini na iindlela zawo kumatyala akhethekileyo njengoyilo oluncamatheleyo.
