Nīnau pinepine ʻia nā Magnets

Hiki iā 'oukou ke paʻi i nā kāleka makana palaka me ke kālai kiʻi?

ʻAe, ʻoiai ʻaʻole hāʻawi ʻia no ke kauoha koke ʻana ma kā mākou pūnaewele (no ka mea hiki ke loli ka nui o nā papahana), hāʻawi mākou iā ia ma ke ʻano he hoʻonohonoho maʻamau. No ka loaʻa ʻana o ke kumu kūʻai, hoʻopihapiha e hoʻopihapiha i kā mākou palapala ʻōlelo maʻamau - ma aneʻi

ʻO ke kekona alumini?

Manaʻo ʻia ʻo Aluminum he non-magnetic ma lalo o nā kūlana maʻamau. He mea paramagnetic ia, ʻo ia hoʻi he nāwaliwali nāwaliwali i nā magnet. ʻAʻole hiki iā ʻoe ke ʻike i kona mau waiwai magnetic i nā ʻike o kēlā me kēia lā. No ka laʻana, ʻaʻole ʻoe e ʻike i kahi lāʻau alumini i kahi magnet fridge. Eia nō naʻe, i ka wā e ʻike ʻia ai i nā māla magnetic ikaika, hiki i ka alumini ke hōʻike i ka magnetism. Hoʻokahi mea ʻoiaʻiʻo, ʻo kā mākou kāleka pāʻoihana magnetic, he magnetic a paʻa i kāu pahu hau e like me ka ʻoihana ʻole a kekahi. Hiki paha iā ʻoe ke hoihoi i kā mākou kāleka ʻoihana metala - noi i kahi ʻōlelo i kēia lā! (kumu kiʻi: https://www.earth.com/earthpedia-articles/aluminum/)

Aia kekahi moʻolelo kuʻuna e pili ana i ke ʻano magnetic o ke kila kila. He nui ka poʻe e manaʻoʻiʻo ana hiki i nā ʻano kila kila a pau ke huki i kahi magnet. ʻAʻole pololei kēlā. ʻO ka mea ʻoiaʻiʻo, hana nā magnet i kekahi mau ʻano kila kila. Nui nā ʻano like ʻole o ke kila kila, akā hiki iā mākou ke hoʻokaʻawale iā lākou i ʻelua mau ʻāpana nui-austenitic a me ferritic. Loaʻa i kēlā me kēia hoʻonohonoho hoʻonohonoho atomika kūʻokoʻa. No kēia kumu, ʻike pinepine mākou i kekahi mau kila kila ʻaʻole magnetic a me nā mea ʻē aʻe. ʻO nā kila kila kila me kahi ʻano ferritic e huki i kahi magnet, aʻo nā ʻano austenitic maʻamau e ... heluhelu hou

He aha nā magnetets i hana ʻia?

Aia nā mākēneki ma nā wahi a pau. Mai kā mākou mīkini kaʻa a hiki i kā mākou kāleka ʻoihana, hoʻohana mākou i nā mea magnet i nā mea āpau i kēia mau lā. Akā naʻe, ʻaʻole maopopo ka hapa nui o mākou i ka mea i hana ʻia ai lākou. ʻO ka hapa nui o nā metala magnetic i hana ʻia e ke kanaka. ʻO nā mea ferromagnetic e like me ka hao, nickel, cobalt, a me kekahi mau alaleʻa o ka ʻene honua laha ʻole hiki ke hoʻopaneʻe ʻia i ka wā e ʻike ʻia ai i kahi māla magnetic ikaika. ʻO nā mea hoʻopaneʻe magnetizing e alakaʻi i ke au uila i nā wahi i hoʻopaʻa ʻole ʻia, kahi e laina ai nā electrons. Ma ka huli ʻana, hana ia i nā mea magnetic. Ma muli o ke ʻano o ka hana ʻia ʻana, hiki i nā magnet ke mālama mau i ko lākou mau waiwai magnetic. … heluhelu hou

He aha nā metala he magnetic?

Hoʻopili ikaika ʻia nā metala ferromagnetic i kahi mana magnetic. ʻO nā metala maʻamau i hoʻohana ʻia ma ke ʻano he mau magnet ka hao, nickel, a me ka cobalt. ʻO nā metala honua laha ʻole e like me neodymium, gadolinium, a me samarium he mau waiwai magnetic ikaika. Hiki i nā mea hao i haku ʻia me nā mea ferromagnetic ke huki i nā magnet. No ka laʻana, ʻo nā kila kuhili ʻole me ka hao kiʻekiʻe he magnetic. ʻO nā hiʻohiʻona ʻē aʻe o nā ferromagnetic alloys e komo pū me chromium a me alnico. Ua kapa ʻia nā metala i hoʻonawaliwali ʻia i nā mea magnetika. ʻO Magnesium, lithium, a me molybdenum kekahi mau hiʻohiʻona o kēia. ʻOi aku ka nāwaliwali o ko lākou ikaika ma mua o nā metala ferromagnetic.

He aha nā hiʻohiʻona āu e hāʻawi ai i nā kāleka pāʻoihana magnetic?

Print PeppermintLoaʻa nā kāleka ʻoihana magnetic kala piha i ʻekolu ʻano kumu: ka maʻamau, ka pōʻai, a me ka oval. Inā makemake ʻoe e hoʻokūpaʻa i kāu ʻoihana, hiki iā mākou ke kōkua iā ʻoe e hana i kahi kāleka hoʻokahi o ke ʻano ma o kā mākou mea hana maʻamau. Hāʻawi pū mākou i nā kāleka pāʻoihana kāhāhā like ʻole e poina ʻole ai kāu brand. ʻO ke ana maʻamau 2 x 3.5 iniha, ʻo ka nui maʻamau he kāleka pāʻoihana ʻano ʻāpana ʻehā. He 17-pt ka mānoanoa o ka waihona magnet. Hiki ke maʻalahi akā paʻa. E pili ana i kona facade, loaʻa iā ia kahi waihona wai-kūpaʻa, i uhi ʻia me ka pau ʻana o UV. ʻO ka Rounder Also… heluhelu hou
