Imagnethi emile okweringi yeNdFeB, ekwabizwa ngokuba yi-neodymium ring magnets, luhlobo lwemagnethi esisigxina ebonisa umngxuma kumbindi weringi. Ezi magnethi zenziwe ngendibaniselwano ye-neodymium, i-iron, kunye ne-boron, kwaye zaziwa ngeempawu zazo eziqinileyo zemagneti kunye nokuqina.
Uyilo olumile okwesangqa kwezi magnethi lubenza bafaneleke ngokufanelekileyo ukusetyenziswa kwimizi-mveliso emininzi nakwizinto zenzululwazi, kuquka iinjini, iijenereyitha, isandisi-lizwi kunye neebheringi zemagnethi. Zisenokusetyenziswa kwiimveliso zabathengi, ezifana ne-magnetic clasps ye-handbag kunye nobucwebe.
Imagnethi emile okwesangqa ye-NdFeB iza ngokobukhulu obahlukeneyo kunye namandla, ukusuka kwiimagnethi ezincinci ezinokungena kwincam yomnwe ukuya kwiimagnethi ezinkulu ezinobubanzi obuyi-intshi ezininzi. Amandla ezi magnethi alinganiswa ngokwamandla abo omhlaba wemagnethi, adla ngokunikezelwa kwiiyunithi ze-gauss okanye i-tesla.
