Iyo na Magneti Yavumbuwe

Magnet ntabwo yahimbwe numuntu, ahubwo ni ibintu bisanzwe bya magneti. Abagereki n'Abashinwa ba kera basanze ibuye risanzwe rifite imbaraga

Yitwa "magnet". Ubu bwoko bwamabuye burashobora gukuramo ibice byicyuma kandi bigahora byerekana icyerekezo kimwe nyuma yo kuzunguruka kubushake. Abatoza ba mbere bakoresheje magneti nka compas yabo ya mbere kugirango berekane icyerekezo cyinyanja. Uwa mbere kuvumbura no gukoresha magnesi agomba kuba Igishinwa, nukuvuga, gukora "kompas" hamwe na magneti nikimwe mubintu bine byavumbuwe mubushinwa.

Mugihe cyibihugu byintambara, abakurambere b'Abashinwa bakusanyije ubumenyi bwinshi kubijyanye na magnet. Iyo bashakishaga amabuye y'icyuma, bakunze guhura na magnetite, ni ukuvuga magnetite (igizwe ahanini na oxyde ferric). Ubu buvumbuzi bwanditswe kera. Ubu buvumbuzi bwanditswe bwa mbere muri Guanzi: "ahari umusozi hari umusozi, munsi ya zahabu n'umuringa."

Nyuma yimyaka ibihumbi yiterambere, magnet yabaye ibikoresho bikomeye mubuzima bwacu. Mugushushanya ibinyobwa bitandukanye, ingaruka zimwe zirashobora kugerwaho nkizya magneti, kandi imbaraga za rukuruzi nazo zirashobora kunozwa. Umuntu yakoze magnesi yagaragaye mu kinyejana cya 18, ariko inzira yo gukora ibikoresho bya magneti ikomeye yatinze kugeza umusaruroAlnicomuri 1920. Nyuma,Ibikoresho bya magnetiyahimbwe kandi ikorwa mu myaka ya za 1950 kandi isi idasanzwe (harimo Neodymium na Samarium Cobalt) yakozwe mu myaka ya za 70. Kugeza ubu, tekinoroji ya magneti yatejwe imbere byihuse, kandi ibikoresho bikomeye bya magnetique nabyo bituma ibice birushaho kuba miniaturizasi.
