Kusiyana pakati pa ng’anjo yopangira induction ndi cupola:

1. The cupola ndi chida chofunikira chosungunula chitsulo choponyedwa mu kupanga. Chitsulo chachitsulo chimasungunuka kukhala chitsulo chosungunula ndikutsanulira mu nkhungu yamchenga kuti uzizirike ndiyeno nkumatsukidwa kuti apeze zotayira. The cupola ndi ofukula cylindrical smelting ng’anjo, amene amagawidwa mu ng’anjo kutsogolo ndi kumbuyo ng’anjo. Kutsogolo kumagawidwanso kukhala dzenje lampopi, dzenje lapopi la slag, malo oyambira kutsogolo kwa chivundikiro cha ng’anjo ndi mlatho. Ng’anjo yakumbuyo imagawidwa m’magawo atatu, ng’anjo yapamwamba, ng’anjo ya m’chiuno ndi moto. Ng’anjo ya m’chiuno imasiyanitsidwa ndi chubu chamoto chotentha, chotsekedwa pambuyo pokonza ng’anjo, ndikusindikizidwa ndi matope. Pamwamba pa ng’anjo pali chotenthetsera kutentha. Amagwiritsidwa ntchito kwambiri popanga zitsulo zachitsulo komanso amagwiritsidwa ntchito popanga zitsulo ndi otembenuza. Chifukwa ng’anjo ya ng’anjo imatseguka m’mwamba, imatchedwa cupola.

2. Ng’anjo yopangira magetsi ndi chipangizo chopangira mphamvu chomwe chimasintha ma frequency a 50HZ osintha ma frequency apakati (pamwamba pa 300HZ mpaka 20K HZ). Imatembenuza magawo atatu amphamvu ma frequency alternating current kukhala yachindunji pambuyo pokonzanso, ndiyeno imatembenuza ma frequency apakati kukhala osinthika apakatikati. Mphamvu yapakatikati yosinthira ma frequency omwe ikuyenda kudzera pa capacitor ndi coil induction imaperekedwa kuti ipange mizere yolimba kwambiri yamagetsi mu koyilo yolowera, ndipo chitsulo chomwe chili mu coil induction chimadulidwa, ndipo mphamvu yayikulu ya eddy imapangidwa mu chuma chachitsulo.
