(Iijika zeDemagnetization zeN40UH Neodymium Magnet)
Iimagnethi ziye zabangela umdla ebantwini kangangeenkulungwane, zibonisa amandla abangel’ umdla abonakala engenakuchazwa. Embindini wamandla umazibuthe kukho igophe le-demagnetization, ingcamango esisiseko ekuqondeni iimpawu zayo zemagnethi. Kule posi yebhlog, siqalisa uhambo lokunciphisa ijika le-demagnetization, sityhila iimfihlo emva kokwakhiwa kwayo kunye nokubaluleka kwayo kwizicelo ezahlukeneyo. Ke, masingene kwihlabathi lemagnethi kwaye siphonononge le nto inomdla!
Ijiko le-Demagnetization libhengezwe
Ijiko le-demagnetization, ekwaziwa ngokuba yi-magnetization curve okanye i-hysteresis loop, ibonisa ukuziphatha kwemathiriyeli kazibuthe xa iphantsi kokutshintsha kwemagnethi. Ibonisa ubudlelwane phakathi kwamandla omhlaba wemagnethi kunye nesiphumo sokungeniswa kozibuthe okanye ukuxinana kweflux. Ngokucwangcisa amandla omhlaba wemagnethi (H) kwi-x-axis kunye noxinano lwemagnethi (B) kwi-y-axis, iijika ze-demagnetization zisivumela ukuba siqonde kwaye sihlalutye iimpawu zemagneti zemathiriyeli.
Ukuqonda iNdlela yokuZiphatha ngeMagnetic Materials
Ngokujonga iigophe ze-demagnetization, sinokuchonga iiparamitha eziphambili ezichaza indlela yokuziphatha kwezinto kwiindawo ezahlukeneyo zemagnethi. Makhe sihlolisise imiba emithathu ebalulekileyo:
1. Indawo yokugcwalisa: Ekuqaleni, i-curve inyuka ngokukhawuleza ide ifike kumda, apho akukho ukwanda kwamandla ombane kuya kuchaphazela ubuninzi be-flux. Eli nqaku libonisa ukuzaliswa kwezinto. Izixhobo ezahlukeneyo zineendawo ezahlukeneyo zokuzalisa, ezimele ukukwazi kwazo ukuhlala zimagnetic phantsi kweendawo eziqinileyo zemagneti.
2. Ukunyanzeliswa: Ukuqhubela phambili kunye ne-curve, amandla amagnetic field ayancipha, okubangelwa ukuhla kwe-magnetic flux density. Nangona kunjalo, xa imathiriyeli igcina iqondo elithile lemagneti, kuya kubakho indawo apho ijika linqumla i-x-axis. Esi siphambuka simele amandla okunyanzeliswa, okanye amandla anyanzelisiweyo, abonisa ukuxhathisa kwemathiriyeli kwi-demagnetization. Izinto eziphathekayo ezinokunyanzeliswa okuphezulu zisetyenziswa kwiimagnethi ezisisigxina okanye ezinye izicelo ezisisigxina zemagneti.
3. Remanence: Xa amandla emagnethi efikelela ku-zero, igophe linqumla i-axis ka-y ukunika ingxinano ye-remanence flux okanye iremanence. Le parameter ibonisa iqondo apho izinto zihlala zimagnetic nasemva kokuba indawo yangaphandle yamagnetic isusiwe. Ukulungiswa okuphezulu kubalulekile kwizicelo ezifuna ukuziphatha okuhlala ixesha elide.
Isicelo kunye nokubaluleka
Iijika ze-demagnetization zibonelela ngengqiqo exabisekileyo ekukhetheni izinto kunye nokuphucula uluhlu olubanzi lwezicelo. Nantsi eminye imizekelo ebalulekileyo:
1. IiMotoli: Ukwazi ijiko le-demagnetization kunceda ekuyileni iimotor ezisebenzayo ezinemathiriyeli yemagnethi ephuculweyo enokumelana neendawo eziphakamileyo zemagneti ngaphandle kokwenza uzibuthe.
2. Ugcino lwedatha yemagnethi: Iigophe zeDemagnetization zinceda iinjineli ukuba ziphuhlise imidiya yokurekhoda enemagnethi enonyanzeliso olwaneleyo lokugcina idatha ethembekileyo kunye neyomeleleyo.
3. Izixhobo zoMbane: Ukuyila ii-inductor cores kunye neziguquli kufuna uqwalaselo ngononophelo lweecurves demagnetization ukuze zilungele iimfuno ezithile zombane kunye nezoomatshini.
Ukuqukumbela
Ngena kwihlabathi lemagnethi ngelensi ye-demagnetization curves, ityhila ubunzima bokuziphatha kwemagnethi kunye nokusetyenziswa kwazo. Ngokusebenzisa amandla eli jiko, iinjineli zivula indlela yenkqubela phambili entsha kuluhlu olubanzi lwamasimi, ukubumba ubume bobuchwepheshe bexesha elizayo. Ke kwixesha elizayo xa udibana nemagnethi, thatha umzuzwana uqonde isayensi emva kwemagnethi yayo kunye neemfihlo ezifihlwe kwigophe elilula le-demagnetization.
