Giraanta NdFeB magnets waa nooc ka mid ah birlab dhulka naadirka ah kaas oo lagu yaqaan xooggiisa sare iyo sifooyinka magnetic. Magnet-yadan waxa laga sameeyay isku-dhafka neodymium, iron, iyo boron, taas oo abuurta goob xoog badan oo birlab ah.
Qaabka rring ee magnet-yadan ayaa ka dhigaya kuwo ku habboon in loo isticmaalo codsiyo badan oo kala duwan, oo ay ku jiraan matoorada, dareemayaasha, kala-soocida magnetic, iyo aaladaha daweynta magnetic. Waxa kale oo loo isticmaali karaa dahabka, farsamada gacanta, iyo ujeedooyinka qurxinta kale.
Giraanta NdFeB magnets waxay ku yimaadaan cabbirro kala duwan iyo xoog badan, oo u dhexeeya birlab yaryar oo ku habboon calaacalaha gacanta ilaa birlab waaweyn oo dhowr inji ah dhexroor. Awoodda birlabyadan waxa lagu cabbiraa marka la eego xooggooda magnetic field, kaas oo inta badan lagu bixiyo unugyo gauss ama tesla ah.
Markaad la tacaalayso giraanta magnets NdFeB, waa muhiim inaad taxaddar muujiso, sababtoo ah waxay noqon karaan kuwo aad u xoog badan oo soo jiidan kara ama celin kara biradaha kale, walxaha birta ah, ama xitaa faraha. Waa in sidoo kale laga fogeeyo aaladaha elegtarooniga ah, sida kuwa garaaca wadnaha ama kaararka deynta, maadaama ay faragelin ku sameyn karaan shaqadooda.
