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 ngeediski ezinzima, iiselfowuni, ii-headphones kunye nezixhobo ezisebenza ngebhetri.Isandi siphezulu.
