Jiilka saddexaad ee dhifka ah ee dhulka birta ah ee birta boron boron (NdFeB) waa magnet joogto ah oo wax qabad sare leh. Ma aha oo kaliya in ay leedahay sifooyinka remanence sare, qasbida sare, wax soo saarka tamarta magnetic sare iyo heerka waxqabadka sare, laakiin sidoo kale waa ay fududahay in la farsameeyo galay qiyaaso kala duwan. Hadda waxaa si ballaaran loo isticmaalaa in aerospace, electroacoustics elektaroonik ah, qalab iyo mitir, accessories farsamada, shandadaha maqaarka, sanduuqyada baakadaha, alaabta lagu ciyaaro In technology caafimaadka iyo qalabka kale ee u baahan beer magnetic joogto ah, waxa ay si gaar ah ku habboon horumarinta qalalan ee alaabta beddelka kala duwan oo leh waxqabadka sare. , yaraynta iyo iftiinka, gaar ahaan magnets disc.
Waxaan sidoo kale soo saari karnaa oo aan taageeri karnaa habeynta tirada badan ee cabbirro kala duwan! Kuwa soo socda waa cabbirradayada caadiga ah. Haddii aadan helin cabbirka aad u baahan tahay, fadlan nala soo xiriir.
