Sharaxaad Gaaban:

Samarium magnet cylinder ama magnet SmCo cylinder waxay qeexaysaa magnet qaab wareegsan oo dhererkeedu ka weyn yahay dhexroorka.Inta badan magnets-ka cylinder SmCo waa axially magnetized, iyo qaar ka mid ah waxaa magnetized diametrically.

Magnets-ka dhululubo ee axially magnetized SmCo, mararka qaarkood waxaa laga yaabaa in loo baahdo tiirar badan oo magnetized dhex dhererka codsiyada gaarka ah qaarkood.Waxaa jira dhowr arrimood oo lagu go'aaminayo in tiirka badan uu magnetized iyo in kaleSmCo magnetwaa suurtagal ama maya, tusaale ahaan, shuruudaha farqiga u dhexeeya tirarka magnetka, cabbirka magnetka, qalabka magnetka, guryaha magnetka, iwm. Way adagtahay in magnet-ka SmCo magnet-ka sinteed loo buuxiyoNdFeB magnet.Haddii cabbirka magnetka ee SmCo uu aad u weyn yahay, magnetizer-ka iyo qalabka magnetization-ku ma dhalin karaan dhul magnetizing ku filan si ay magnetize SmCo magnet si saturation ah.Caadi ahaan dhumucda magnetka SmCo ayaa looga baahan yahay inay ka hooseyso 5 mm, mararka qaarkoodna Hcj waa in lagu xakameeyaa agagaarka ama aan ka badnayn 15kOe.Kahor soo saarista tirada badan, muunada magnet-ka tiirarka badan waa in lagu ansixiyo imtixaanada dhamaystiran ee macaamiisha si loo buuxiyo shuruudaha codsiga.

SmCo Sylinder Magnets Iibiyaha

Mararka qaarkood, magnets-ka cylinder SmCo ayaa laga yaabaa inuu u baahdo dhejis.Si ka duwan sintered Neodymium magnet si fudud loo oksaydhize, Samarium Cobalt magnet waa ku fiican yahay iska caabin daxalka ay sabab u tahay ka kooban walxaha gaar ah oo aan Fe ama leh oo kaliya ku dhawaad ​​15% birta.Sidaa darteed codsiyada intooda badan, dahaarka looma baahna magnet SmCo si looga hortago daxalka.Si kastaba ha noqotee, goobaha codsiyada qaarkood, magnet SmCo ayaa looga baahan yahay in lagu dahaadho dahab dhalaalaya ama quruxsan ama Nickel si loo gaaro muuqaal qumman.

Marka macaamiishu go'aansadaan qalabka magnetka ee ku habboon codsigooda, waxay sidoo kale daneeyaan sifooyinka jirka.Kuwa soo socda ayaa ah sifooyin jireed oo loogu talagalay magnets-ka SmCo:
