Kodi maginito a NdFeB ndi chiyani?

NdFeB maginito, ndi maginito osowa padziko lapansi omwe amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndi malonda chifukwa cha mphamvu zawo zamaginito.Maginitowa amadziwika ndi mphamvu zawo zazikulu, kukana demagnetization, komanso mtengo wotsika, zomwe zimawapangitsa kukhala odziwika pazida zosiyanasiyana zamagetsi, zida zamankhwala, ndi makina.

Kapangidwe kaNdFeB maginitondizovuta kwambiri, koma ndizovuta izi zomwe zimawapatsa mawonekedwe awo apadera.Maginitowa amapangidwa kuchokera ku neodymium, iron, ndi boron, ndi zinthu zina zazing'ono zomwe zimawonjezeredwa kuti ziwongolere maginito.Chinsinsi cha mphamvu yake yapadera ya maginito ndi momwe ma atomu amapangidwira mkati mwa kristalo wa zinthuzo.

Kapangidwe ka kristalo waNdFeB maginitondi tetragonal lattice momwe ma atomu a neodymium ndi boron amapanga zigawo mkati mwa dongosolo la lattice ndipo maatomu achitsulo amakhala pakati pa zigawozi.Kapangidwe kapadera kameneka ka ma atomu kumayendera limodzi ndi mphamvu ya maginito ya ma atomu, n’kupanga mphamvu ya maginito.

Kuphatikiza pa mawonekedwe awo apadera a kristalo,NdFeB maginitonthawi zambiri amapangidwa m'mawonekedwe ndi makulidwe osiyanasiyana, kuphatikiza mapepala, ma disks, ndi midadada, kuti zigwirizane ndi ntchito zosiyanasiyana.Makamaka,Gawo la Ndfeb maginitoamagwiritsidwa ntchito kwambiri popanga ma motors, ma jenereta, olekanitsa maginito ndi makina a maginito a resonance imaging (MRI) chifukwa cha mphamvu zawo zamaginito komanso kukhazikika.

Mwachidule, kapangidwe ka maginito NdFeB ndi chinthu chofunika kwambiri maginito katundu wawo.Tetragonal lattice, kuphatikizidwa ndi makonzedwe enieni a neodymium, chitsulo ndi ma atomu a boron, amalola maginitowa kuwonetsa mphamvu zamaginito komanso kukana demagnetization. Gawo la Ndfeb maginito, makamaka, ndi gawo lamtengo wapatali pa ntchito zosiyanasiyana za mafakitale ndi zamalonda zomwe zimafuna maginito amphamvu komanso okhazikika.
