Unomphela Samarium Cobalt Magnets SmCo Magnet
Incazelo Yomkhiqizo
Ozibuthe be-Samarium-Cobalt (SmCo) bane-coefficient yezinga lokushisa elingcono kakhulu le-Br (-0,035%/℃) enikeza ukungeniswa okuphezulu okutholakalayo okungaphezu kuka-150℃ lokushisa lokusebenza. Naphezu kwezindleko eziphakeme kunezinye izinto kazibuthe, i-SmCo inikeza inhlanganisela evelele yamandla aphezulu, ukuzinza okushisayo, nokumelana nokugqwala. Izingubo zokuzivikela ngokuvamile azidingeki ngaphandle kwezicelo ezithile. Kepha i-SmCo icwebile futhi ithambile: uma uyiwisa, izophuka.
