Chitetezo cha Magnet:
Maginito osowa padziko lapansi kapena maginito ndi amphamvu kwambiri, kotero njira zodzitetezera zili pansipa ziyenera kudziwidwa kwa onse ogwira ntchito, kuzigwira, kapena kuzipanga kuti apewe kuvulala kapena kuwonongeka kwa maginito.
Onetsetsani kuti maginito osowa maginito padziko lapansi ali pansi pa ulamuliro pamene akhudzana wina ndi mzake kapena ferromagnetic zipangizo.Ndikofunikira kuvala magalasi oteteza chitetezo ndi zida zina zodzitetezera pogwira maginito akulu.Kuvala magolovesi kuti muteteze manja kumalimbikitsidwanso.
Sungani zitsulo za ferromagnetic kutali ndi malo ogwirira ntchito.Samalani mukamagwira ntchito ndi maginito.Osagwira ntchito ndi maginito amagetsi ngati mwamwa mowa, mankhwala osokoneza bongo, kapena zinthu zolamulidwa.
Zida ndi zida zamagetsi zowoneka bwino zitha kusintha masinthidwe kapena kuonongeka ndi mphamvu ya maginito.Nthawi zonse sungani maginito a maginito kutali ndi zida zamagetsi zomwe zimakhudzidwa.Chenjezo lapadera liyenera kuchitidwa ngati munthu wavala pacemaker, chifukwa mphamvu ya maginito imatha kuwononga zamagetsi mkati mwa makina othamanga.
Osameza maginito kapena kuyika maginito pamalo omwe ana kapena akuluakulu omwe ali ndi vuto loganiza angafikire.Ngati maginito amezedwa, funsani dokotala nthawi yomweyo ndi/kapena funsani kuchipatala.
Magineti osowa padziko lapansi amatha kupanga zowala polumikizana pogwira, makamaka akaloledwa kukhudza limodzi.Osagwira maginito osowa padziko lapansi m'malo ophulika chifukwa kutentha kumatha kuyatsa mlengalenga.
Ufa wapadziko lapansi wosowa ukhoza kuyaka;kuyaka modzidzimutsa kumatha kuchitika ufa ukauma.Ngati akupera, nthawi zonse chonyowa pogaya maginito kupewa mowiriza kuyaka wa akupera swarf.Osawumitsa pogaya.Onetsetsani kuti muli ndi mpweya wokwanira popera maginito.Osayesa kupanga maginito pogwiritsa ntchito zida wamba, chifukwa izi zitha kutulutsa ndikuphwanya.Nthawi zonse muzivala magalasi otetezera.
Nthawi zonse sungani ufa wadothi wosowa kapena pogaya m'mitsuko yodzadza ndi madzi kapena mumlengalenga wotsekedwa ndi hermetically kuteteza kuyaka kochitika.
Nthawi zonse taya ufa wapadziko lonse mosamala.Osawotcha moto.Kutaya maginito maginito kuyenera kuchitidwa pofuna kupewa kuvulala mukamagwira.
