Mbiri Yachidule ya Zida za Maginitsi

China ndi dziko loyamba ladziko lapansi kuti lipezeke ndikugwiritsa ntchito maginito . Pofika nthawi yolimbana ndi nkhondo, panali zolemba za maginito achilengedwe (monga maginito). Njira yopangira maginito osatha zomwe zidapangidwa m'zaka za zana la 11. Mu 1086, Mengxi Biban adalemba ndikugwiritsa ntchito kampasi. Kuyambira pa 1099 mpaka 1102, kampasi idagwiritsidwa ntchito polemba zolemba, ndipo chodabwitsa cha kuchepa kwa geomagnetic chidapezekanso. Masiku ano, kukula kwa mphamvu yamagetsi yamagetsi yalimbikitsa chitukuko cha maginito achitsulo sicneti achitsulo (sil alloy). Zitsulo zakuthambo zakuthambo zayamba chifukwa cha kaboni m'zaka za zana la 19 kuti apatsidwe mphamvu zachilengedwe za dziko lapansi, ndipo ntchito yake yakhala zikuyenda bwino nthawi 200. Ndi chitukuko cha ukadaulo wolumikizirana, zida zofewa zamagetsi sizimatha kukwaniritsa zofunikira za kuchuluka kwa mapepala kuchokera pa waya kenako mpaka ufa. Mu 1940s, jl snojk wa Netherlands adapanga zofewa zamagetsi zotsika kwambiri komanso zomwe zimakhala ndi mbiri yabwino kwambiri komanso zotsika mtengo zotsika mtengo. Kumayambiriro kwa m'ma 1950, ndikukula kwa makompyuta amagetsi, aku American waku America, adagwiritsa ntchito koyamba maginito Kukula kwa makompyuta mu 1960s ndi 1970s. Kumayambiriro kwa zaka za m'ma 1950, anthuwa adapeza kuti Ferrite anali ndi mawonekedwe apadera a microwave ndipo adapanga zida zamagetsi zingapo. Zipangizo za Piezzomagnetic zakhala zikugwiritsidwa ntchito mu ukadaulo wa soser kuyambira nkhondo yoyamba yapadziko lonse lapansi, koma kugwiritsa ntchito kwachepa chifukwa chazomera za piezooelectric. Pambuyo pake, dziko lapansi lamsere limafotokoza zambiri zomwe zimapangitsa kuti maginito ambiri atuluke. Amorphous (amorphous) maginito ndi omwe amakwaniritsa kafukufuku wamatsenga amakono. Pambuyo popanga ukadaulo wowuma mwachangu, njira yokonza tepi idathetsedwa mu 1967, yomwe ikusintha.
