I-conductivity yombane ye-graphite ilungile kakhulu, idlula iintsimbi ezininzi kunye namaxesha angamakhulu ee-non-metals, ngoko ke iveliswa kwiindawo eziqhubayo ezifana ne-electrodes kunye ne-carbon brushes;
Indima ethile yebrashi yekhabhoni
Iimagnethi zeNdFeB ngoku zezona magnethi zinamandla asisigxina.
Iimoto ezingenabhurashi ikakhulu zisebenzisa iimagnethi zomhlaba ezinqabileyo zeNdFeB ngokusebenza okuphezulu,
