Kukwera mwachangu kwamitengo ya maginito a NdFeB mu 2021 kumakhudza zokonda zamagulu onse, makamaka opanga mapulogalamu otsika. Amafunitsitsa kudziwa za kupezeka ndi kufunikira kwa maginito a Neodymium Iron Boron, kuti akonzeretu mapulani amtsogolo ndikutenga zochitika zapadera ngati dongosolo. Tsopano tipereka lipoti lachidule lachidziwitso cha maginito a NdFeB ku China kwa makasitomala athu, makamaka opanga magalimoto amagetsi kuti afotokozere.
M'zaka zaposachedwapa, linanena bungwe la NdFeB okhazikika maginito zipangizo ku China wasonyeza mchitidwe kukula.Sintered NdFeB maginitondi mankhwala ambiri mu zoweta NdFeB okhazikika maginito msika. Malinga ndi deta ya Unduna wa Makampani ndi Information Technology, linanena bungwe la sintered NdFeB akusowekapo ndi womangidwa NdFeB maginito ndi matani 207100 ndi matani 9400 motero mu 2021. % chaka ndi chaka.
Mtengo wa maginito osowa padziko lapansi wakwera kwambiri kuyambira nthawi yotsika pakati pa 2020, ndipo mtengo wa maginito osowa padziko lapansi wawonjezeka kawiri kumapeto kwa 2021. Praseodymium, Neodymium, Dysprosium, Terbium, akwera mofulumira. Pofika kumapeto kwa 2021, mtengo uli pafupi katatu mtengo wapakati pa 2020. Kumbali imodzi, mliriwu wachititsa kuti anthu azikhala osauka. Kumbali ina, kufunikira kwa msika kwakula mofulumira, makamaka chiwerengero cha ntchito zowonjezera zatsopano za msika. Mwachitsanzo, maginito onse osowa padziko lapansi okhazikika a magalimoto amphamvu aku China amakhala pafupifupi 6% ya sintered Neodymium maginito linanena bungwe mu 2021. %. Magalimoto onyamula magetsi oyeretsera adzakhalabe mtundu wa magalimoto atsopano opangira mphamvu. Mu 2021, matani 12000 amaginito apamwamba a NdFeBamafunikira m'munda wa magalimoto amagetsi. Akuti pofika chaka cha 2025, kuchuluka kwapachaka kwamphamvu kwagalimoto yaku China kudzafika 24%, kuchuluka kwa magalimoto atsopano amphamvu kudzafika 7.93 miliyoni pofika 2025, ndipo kufunikira kwa maginito atsopano osowa padziko lapansi a Neodymium. 26700 matani.
Pakali pano China ndi dziko lalikulu kwambiri padziko lonsewopanga maginito osowa padziko lapansi, ndipo zotsatira zake zakhalabe pamwamba pa 90% ya chiwerengero cha padziko lonse m'zaka zaposachedwa. Kutumiza kunja ndi amodzi mwa njira zazikulu zogulitsira zinthu zachilendo padziko lapansi za maginito ku China. Mu 2021, kuchuluka kwa katundu wosowa padziko lapansi kwanthawi yayitali ku China ndi matani 55000, kuchuluka kwa 34.7% kuposa 2020. chifukwa chakuchulukirachulukira kwa maginito aku China osowa padziko lapansi omwe amatumizidwa kunja.
Europe, America ndi East Asia nthawi zonse akhala misika yayikulu yogulitsa kunja kwazinthu zakunja zaku China za Neodymium maginito. Mu 2020, kuchuluka kwathunthu kwa mayiko khumi omwe adatumizidwa kunja kudaposa matani 30000, kuwerengera 85% yachiwonkhetso; chiwerengero chonse cha mayiko asanu omwe ali pamwambawa chinaposa matani 22000, zomwe zimapanga 63% ya chiwerengero chonse.
Kuchuluka kwa msika wa maginito achilendo padziko lapansi ndikwambiri. Malinga ndi zomwe zimagulitsidwa kunja kwa mabizinesi akuluakulu, maginito ambiri osowa padziko lapansi aku China amatumizidwa ku Europe, United States ndi East Asia, ambiri mwa mayiko otukuka omwe ali ndi sayansi komanso luso lapamwamba kwambiri. Kutengera zomwe zatumizidwa mu 2020 mwachitsanzo, mayiko asanu apamwamba ndi Germany (15%), United States (14%), South Korea (10%), Vietnam ndi Thailand. Akuti malo omalizira a maginito osowa padziko lapansi omwe amatumizidwa ku Southeast Asia makamaka ku Ulaya ndi America.
