Urwego rwohejuru NdFeB Magnet kuva iburasirazuba
Imbaraga zidasanzwe zo muburasirazuba,
yarazwe imyaka ibihumbi, byasabwe na Confucius
Abantu b'indashyikirwa
igihe gikwiye n'ahantu heza
Mu nyandiko zo mu gihe cyimpeshyi nigihe cyizuba hamwe nigihe cyibihugu byintambara, ibintu bikurura ibyuma byarukuruzibyanditswe inshuro nyinshi.Kurugero, "ibuye rya magnetique rihamagarira icyuma" muri "Lu Shi Chun Qiu" ryanditswe mu kinyejana cya gatatu mbere ya Yesu, naho "ibuye rya rukuruzi rihamagarira urushinge" muri "Guiguzi" ritari kure yandi yombi.Muri iki gihe, magnetism birashoboka ko byari bisanzwe bizwi kandi ugereranije no gukurura umubyeyi wuje urukundo kubana be.
Gao Yao wo mu Bwami bw'Iburasirazuba bwa Han yavuze mu magambo ye yise "Lu Shi Chun Qiu": Ibuye ni nyina w'icyuma, ariko hariho amabuye meza kandi atuje.Ibuye ryiza rishobora gukurura abana baryo (icyuma), ariko ibuye ritameze neza ntirishobora gukurura..Kubwibyo, mbere yingoma ya Han, magnesi zanditswe nka "Ci Shi", bisobanura "Ibuye ryineza".
Nyuma, byanze bikunze abantu bakoresheje magnesi kugirango bagerageze gukurura ibindi byuma cyangwa ibintu.Ingaruka zabaye izihe?
Igitabo "Huainanzi" cyanditswe mu ngoma y’iburengerazuba bwa Han cyanditse ngo: "Niba ibuye ryiza rishobora guhuza ibyuma, bizagorana kuyikoresha mu kuyobora amabati.""Ntishobora guhuza umuringa."Mu gihe cy'Ubwami butatu, umuntu na we yagize ati: "Ibuye ry'ineza ntirishobora kugororwa."Ibyo bita "inshinge zigoramye" birashoboka ko byerekeza ku nshinge zikoze mu byuma nka zahabu, ifeza, n'umuringa, birumvikana ko bidakururwa na magnesi.
Izi nyandiko zerekana ko Ingoma ya Han yamenye ko magnesi zishobora gukurura ibyuma gusa ariko ntibikure mubindi bintu.Iri ni iterambere.Turabizi ko magnesi zishobora gukurura gusa ibyuma, ariko niba magnesi zegeranye, ibintu birakomeye.Imashini zihora zifite inkingi ebyiri, imwe yitwa pole yepfo indi yitwa pole y'amajyaruguru.Icyo gihe, hari an alchemiste witwa Luan Da wakoze magnesi ebyiri, zasa nkibice bya chess kandi byari hafi yundi.Byaravuzwe ko badashobora gukururana gusa ("guhagarika undi"), ariko kandi "bakirukana ubuziraherezo", ni ukuvuga kwamagana.Ubu ni bwo buryo bwitwa "kurwanya chess".Yakoresheje amayeri Umwami Wu w'ingoma ya Han,naumwami w'abami yarishimye, nuko abona umwanya wa "Jenerali-Inyungu eshanu".
