1. Wokamba maginito ali ndi electromacagnetnetnetnetnetnetnetnetnes pakati pa mitengo iwiri ya maginito okhazikika. Pakakhala zapano pa coil wa electromacagnet, core core core imakopeka ndi gawo la magawo awiri a maginito awiri a maginito a maginito okhazikika ndipo amakhalabe pakati; Pakadutsa makanema kudzera mu coil, maziko achitsulo amasunthika ndipo amakhala a maginito. Posintha malangizo apano, porlaty wa bar magnet amasinthanso chimodzimodzi, ndipo kugwedeza kwa core chitsulo chosunthika kumachokera ku cartilegm (pepala la pepala) kukankhira mpweya.

2. Wokamba nkhani wamagetsi ndi wokamba nkhani yemwe amagwiritsa ntchito mphamvu yamagetsi yowonjezeredwa ku mbale ya papaku. Potengera kapangidwe kake, imatchedwanso wokamba nkhani chifukwa ma elekitirodi ndi oyipa komanso olakwika amakhala oyang'anizana. Zipangizo ziwiri zolimba komanso zolimba zimagwiritsidwa ntchito ngati mbale zokhazikika, zomwe zimatha kufalitsa mawu, ndipo mbale yapakati imapangidwa ndi zida zowonda komanso zopepuka ngati ma diaphragms (monga aluminium ma diaphragms). Konzani ndikulimba mozungulira diaphragm ndikusunga mtunda wautali kuchokera pamtengo wokhazikika. Ngakhale pa diaphragm yayikulu, sichingagunde ndi mtengo wokhazikika.
3. Phenomenon kuti diectric (monga quartz, potaziyamu sodium tartate ndi makhiristo ena) amasandulika pakati pa malekezero awiriwa, omwe amatchedwa "piezoelertric profts. Zovuta zake, ndiye kuti, kuwonongeka kwa madeti ku dielectric poikidwa mu magetsi, kumatchedwa "zotsekemera pizolectric sof" kapena "elenterfestriction".
