Uruganda rugurisha rutaziguye, imipira ya magneti.Ibyiza byibicuruzwa byacu:
1. Ugereranije nabandi batanga isoko bakoresha N35 yo mu rwego rwo hasi, uruganda rwacu rukoresha urwego rwa N38 kugirango rukore magnetism ikomeye.
2. Ibice bitanu nano irangi ryerekana kugirango ubuso burambye cyane kubana gukina.
3. Dufite diameter zitandukanye namabara yumupira, diameter 3mm na 5mm nubunini busanzwe, duhindura diameter zitandukanye ubu bwoko bwumupira wa magneti.
