Umxube ongeyo-homogeneous we-magnetite, isinyithi, i-oksijini kunye nezinye izinto ezilandelwayo kwi-lodestone, imagnethi eyenzeka ngokwemvelo, yinto eyenza isigxina (inzima).I-magnetite ecocekileyo ye-homogeneous okanye intsimbi ayisigxina kodwa yimagnethi yethutyana (ethambileyo).Eyona nto ifanelekileyoumazibuthe osisigxinayingxubevange ene-heterogeneous ene-coercivity ephezulu, okuthetha ukuba kunzima ukwenza i-demagnetize.Ezi ngxubevange zineeathom ezinokuthi zifunyanwe ukuba zikhombe ngokuzingileyo kwicala elinye (iferromagnetic) zizenza zibe zimagnetic ngamandla.Zintathu kuphela i-iron, i-cobalt kunye ne-nickel-kwii-elementi ze-100 kwi-periodic table ezi-ferromagnetic kubushushu begumbi.I-alloys zenziwa zimagnetic ngokuzibeka kwimagnethi okanye i-electromagnets.
Khupha kwisandisi-lizwi.
Sebenzisa iitoni ukufudumeza isikhonkwane sentsimbi phezu kwesitovu, ukuvumela iiathom ezikwisikhonkwane ukuba zijikeleze ngokukhululekileyo.
Sebenzisa ikhampasi ukumisela iipali zoMhlaba ezinozibuthe ezingasentla nasezantsi.Lungelelanisa isikhonkwane sentsimbi kwicala leNorth-South kwaye ubeke iiimagnethi zesithethiemantla nje isikhonkwane.
Betha isikhonkwane ngehamile de kuphole, ubuncinci amaxesha angama-50, uqinisekise ukuba isikhonkwane sihlala sihlala kwicala elingasentla ukuya emazantsi.Iiathom ezingaphakathi kwesikhonkwane sentsimbi ziya kushukunyiswa ukuze zihambelane nemagnethi yemagnethi ekufutshane.
Iingcebiso kunye nezilumkiso
Ezinye izinto eziqhelekileyo zendlu, ezifana ne-oven microwave, nazoIimagnethi zomhlaba ezomeleleenokusetyenziswa endaweni yemagnethi yesandisi-lizwi.Okona kunamandla umazibuthe, kokukhona iziphumo zingcono.
Imagnethi yomhlaba iyodwa inako ukwenza buthathaka isikhonkwane sentsimbi, ngaphandle kokusebenzisa umazibuthe wesandisi-lizwi.
Ukukhetha imathiriyeli eyomeleleyo ye-ferromagnetic ukwenza imagneti kuya kuvelisa iziphumo ezingcono.
Abantwana kufuneka babe phantsi kweliso labantu abadala xa besenza le projekthi.
Iimagnethi ziyakwazi ukucima idatha egcinwe ngokwemagnethi kwizinto ezinjengeeteyiphu zevidiyo, iihard drives kunye namakhadi okuthenga ngetyala.
