Ipropathi yokufunxa intsimbi yemagnetite ifunyenwe ixesha elide.Kwimiqulu esithoba yentwasahlobo kaLu kunye ne-Autumn Annals, kukho intetho ethi: "ukuba unomusa ngokwaneleyo ukutsala isinyithi, unokukhokelela kuyo."Ngelo xesha, abantu babebiza "imagnetism" ngokuthi "ububele".Babeyijonga intsimbi etsala umazibuthe njengomtsalane kamama ebantwaneni bakhe.Ucinga ukuba: "ilitye ngumama wentsimbi, kodwa kukho iindidi ezimbini zamatye: ilitye elinothando linokutsala abantwana bakhe, kodwa ilitye elingenambulelo alikwazi."Ngaphambi kobukhosi bukaHan, abantu babhala "uCi Shi", oku kuthetha ilitye elinothando.
Ekubeni i-magnetite inokutsala isinyithi, ingaba inokutsala nezinye iintsimbi?Ookhokho bethu benza iinzame ezininzi, kwaye bafumanisa ukuba imagnethi ayinakutsala kuphela igolide, isilivere, ubhedu kunye nezinye isinyithi, kodwa kunye nezitena kunye neetayile.Kwi-Western Han Dynasty, abantu sele beqaphele ukuba i-magnetite inokutsala isinyithi kuphela, kunezinye izinto.Xa oomazibuthe ababini bebekwe kufutshane omnye komnye, ngamanye amaxesha bayatsalana kwaye ngamanye amaxesha bayagxothana.Kuyaziwa ukuba iimagnethi zineepali ezimbini, enye ibizwa ngokuba yi-N pole kwaye enye yi-S pole.Njengeepali zigxotha enye kwenye, iipali ezichaseneyo zitsala enye kwenye.Abantu ngelo xesha babengayazi le nyaniso, kodwa babesenokuyibhaqa.
Kwi-Western Han Dynasty, kwakukho i-alchemist egama linguLuan da.Wenza iziqwenga ezibini zechess njengezinto ngokulungelelanisa i-polarity yeziqwenga ezimbini.Ngamanye amaxesha ezi ziqwenga zimbini zitsala umdla omnye komnye, kwaye ngamanye amaxesha zazigxothana.ULuan Da wayibiza ngokuba yi "Dou Qi".Wanikezela ngenoveli kuMlawuli uWu woBukhosi bakwaHan kwaye wayibonisa kwangoko.UMlawuli uWu woBukhosi bakwaHan wakhwankqiswa, kwaye uLongxin wavuya kakhulu kangangokuba uLuan wanikwa iwonga lokuba "yiNjengele yaseWuli".ULuan Da wasebenzisa ubume bemagnethi ukwenza izinto ezinoveli ukukhohlisa uMlawuli uWu weHan Dynasty.
Umhlaba ukwangumazibuthe omkhulu.Iipali zayo ezimbini zikufuphi ne-geographical South pole kunye ne-geographical North pole ngokulandelelanayo.Ngoko ke, xa iimagnethi ezisemhlabeni ziyakwazi ukujikeleza ngokukhululekileyo, ziya kugxotha omnye komnye kunye nemagnethi efanayo, kwaye zitsale imagnethi ngezinto ezahlukeneyo, ezibonisa umntla nasezantsi.Abantu bakudala babengayiqondi le nyaniso, kodwa babecace gca ngolu hlobo lweziganeko.
