I-Neodymium Iron Boron Magnets yenye yezona magnethi zinamandla zorhwebo ezikhoyo namhlanje. Ezi magnethi zomhlaba zinqabileyo zinokomelela ngokuphindwe ka-10 kunemagnethi yeceramic eyomeleleyo. Iimagnethi ze-NdFeB zihlala ziveliswa kusetyenziswa enye yeendlela ezimbini zeendlela eziqhelekileyo, iimagnethi ezibotshiweyo (uxinzelelo, inaliti, i-extrusion okanye ukubumba ikhalenda), kunye nemagnethi edibeneyo (isinyithi somgubo, inkqubo ye-PM). Iimagnethi ze-NdFeB zihlala zisetyenziswa kwiimveliso ezifuna iimagnethi ezomeleleyo ezinje ngehard disk drives yeekhompyuter, iimotor zombane kwizixhobo ezingenantambo, kunye neziqhoboshi. Ukusetyenziswa kwecandelo lezonyango usetyenziso olutsha kwezi magnethi zinamandla ziyavela. Umzekelo, ukuzulazula kwecatheter, apho iimagnethi zinokudityaniswa kwincam yendibano yecatheter kwaye ilawulwe ziinkqubo zangaphandle zemagnethi zokuqhuba kunye nokuphambuka.
Olunye usetyenziso kwicandelo lezonyango lubandakanya ukwaziswa kweeskena ze-open magnetic resonance imaging (MRI) ezithi zisetyenziswe ukwenza imephu kunye ne-anatomy yomfanekiso, njengenye indlela yemagnethi esebenza kakhulu edla ngokusebenzisa iikhoyili zocingo ukuvelisa umhlaba wemagnethi. Ukusetyenziswa okongeziweyo kwintsimi yesixhobo sonyango kubandakanya, ukufakelwa kwexesha elide kunye nexesha elifutshane, kunye nezixhobo ezincinci ezihlaselayo. Ezinye izicelo ezihlaselayo kancinane kwimagnethi yentsimbi ye-neodymium zebhoron ziindibano ze-endoscopic zeenkqubo ezininzi ezibandakanya; i-gastroesophageal, i-gastroesophageal, i-skeleton, imisipha kunye namalungu, i-cardiovascular, kunye ne-neural.
Iimagnethi zeFerrite, iimagnethi zeneodymium okanye iziseko zemagnethi zisetyenziselwa iintlobo ngeentlobo zezicelo kubuchwephesha, kushishino nakwinjongo zonyango. Kukho imfuneko yokubonelela ngeemagnethi ngokhuseleko olungaphezulu kumhlwa, “ukwaleka” kweemagnethi. Ukufakwa kwemagnethi ye-neodymium yinkqubo ebalulekileyo yokukhusela umazibuthe ekudlekeni. I-substrate i-NdFeB (i-Neodymium, i-Iron, i-Boron) iya ku-oxidize ngokukhawuleza ngaphandle koluhlu olukhuselayo. Apha ngezantsi kukho uludwe lokutyabeka/ukwaleka kunye neentsiba zazo kwireferensi yakho.
