Madulidwe amagetsi a graphite ndiabwino kwambiri, kuposa zitsulo zambiri komanso nthawi mazana ambiri zomwe sizitsulo, motero amapangidwa kukhala magawo opangira ma elekitirodi ndi maburashi a kaboni;
Ntchito yeniyeni ya carbon burashi
Maginito a NdFeB pakadali pano ndi maginito amphamvu kwambiri okhazikika.
Ma motors opanda maburashi amagwiritsa ntchito maginito osowa padziko lapansi a NdFeB omwe amagwira ntchito kwambiri,
