Xa umsinga oguqukayo ufakwa kwisandi, umazibuthe uba ngumazibuthe. Isalathiso sangoku sitshintsha rhoqo, kwaye i-electromagnetic iqhubeka ihamba phambili naphambili ngenxa "yentshukumo yokunyanzeliswa kocingo olunamandla kwintsimi yamagnetic", iqhubela i-basin yephepha ukungcangcazela ngasemva naphambili. I-stereo inesandi.
Iimagnethi ezisephondweni ikakhulu zibandakanya imagnethi yeferrite kunye nemagnethi yeNdFeB. Ngokwesicelo, iimagnethi zeNdFeB zisetyenziswa kakhulu kwiimveliso zombane, ezinje ngehard disks, iiselfowuni, ii-headphones kunye nezixhobo ezisebenza ngebhetri. Isandi siphezulu.
