He Aluminum Magnetic?

1. Hōʻikeʻike

ʻO ka pane pōkole: aluminum ʻAʻole magnetic i ke ʻano o kēlā me kēia lā. ʻAʻole ia e like me ka hao, Kukui Kekuhi, nickel, a i ʻole kobalta, hiki ke huki ikaika ʻia i nā magnet.

Akā naʻe,, ʻoi aku ka nuanced o ka pane ʻepekema piha. Loaʻa i ka alumini ka pane magnetic nāwaliwali, a ma lalo o kekahi mau kūlana hiki iā ia ke launa pū me nā māla magnetic ma nā ala e kahaha ai nā kānaka.

He mea nui kēia ʻokoʻa ma muli o ka ʻōlelo magnetic hoʻohana nui ʻia i ke ola o kēlā me kēia lā. Ma ka ʻepekema a me nā mea waiwai, ʻAʻole hoʻokahi hanana ka magnetism akā he ʻohana o nā ʻano.

ʻO ka alumini kekahi o nā māhele nāwaliwali, ʻaʻole ka papa ikaika i manaʻo ʻia e ka hapa nui o ka poʻe.

2. He aha ke ʻano o "Magnetic".

Ke nīnau mai ka poʻe inā he magnetic kekahi mea, ʻO ka manaʻo maʻamau kekahi o nā mea ʻekolu:

• Pili paha i ka magnet?
• Hiki iā ia ke huki ikaika ʻia e kahi māla magnetic?
• Hiki iā ia iho ke lilo i magnet mau?

Hana ʻo Aluminum ʻaʻole e hana i kekahi o ia mau mea ma ke ʻano o nā metala ferromagnetic.

Mai ka ʻike ʻepekema, hui pū ʻia nā mea like:

• Ferphanevic: hiki ke hoʻopaʻa i ka magnetization, e like me ka hao a me ke kila.
• Pamagnetic: huki ikaika ʻia i nā māla magnetic.
• Diamagnetic: hoʻokuʻu nāwaliwali ʻia e nā māla magnetic.

Alumini Pamagnetic, ʻo ia hoʻi, ua nawaliwali wale ka huki ʻia ʻana i kahi māla magnetic. He liʻiliʻi kēlā hopena, ma ka hoohana mau, Hana ʻia ka alumini ma ke ʻano he non-magnetic.

3. Ka Aluminum's Intrinsic Magnetic Behavior

Alumini ʻaʻole ferromagnetic. ʻAʻole ia i ka ʻōnaehana domain kūloko e hiki ai i ka hao, nickel, a i ʻole kobalt e lilo i mea magneti ikaika a i ʻole e hoʻopaʻa i ka magnetization ma hope o ka wehe ʻia ʻana o ke kahua o waho. Ma kēlā manaʻo i kēlā me kēia lā, ʻAʻole ʻo ka alumini he "metala magnetika."

Mai ka manaʻo physics, Akā naʻe,, alumini Pamagnetic. 'O ia ho'i, he nāwaliwali loa kona, pane maikaʻi i kahi kahua magnetic i hoʻohana ʻia.

Loaʻa ka hopena mai ke ʻano o kāna mau electrons: i ka wā e hōʻike ʻia ai i kahi māla magnetic, Hoʻokumu ka alumini i kahi alignment liʻiliʻi e hoʻoikaika iki i ka māla. He ʻoiaʻiʻo a hiki ke ana ʻia kēlā pane, aka, he uuku loa.

He waiwai electromagnetic koʻikoʻi ka alumini e hoʻohaunaele pinepine ai.

No ka mea, he conductor uila maikaʻi, ka hoʻoneʻe ʻana i ka alumini ma o ke kahua hoʻololi, a i ʻole ka hoʻoneʻe ʻana i kahi māla magnetic e pili ana i ka alumini, hiki ke hana eddy au i ka metala.

Hoʻokumu kēlā mau au i kā lākou mau māla magnetic kū'ē, hiki ke hana i nā mana ʻike e like me ka braking a i ʻole ke kauo.

ʻAʻole like kēia me ka huki ʻana i ka magnetically i ka manaʻo ferromagnetic; he hopena induction ma muli o ka conductivity.

Pela, ʻepekema, ʻO ka alumini ka mea i wehewehe maikaʻi ʻia paramagnetic nāwaliwali, uila uila, a me ka non-ferromagnetic.

4. No ke aha i manaʻo pinepine ʻia ai ka alumini "Non-Magnetic"?

Kapa pinepine ʻia ka alumini non-magnetic no ka mea, ma ka hoohana maa mau, ʻAʻole ia e hana e like me ka mea magnetik.

ʻAʻole e hoʻopili ʻia kahi magnet refrigerator, ʻaʻole lilo ia i mea magnetized mau loa, ʻaʻole ia e hōʻike i ka manaʻo ikaika e pili ana i ke kila a me ka hao.

He mea maikaʻi kēia wehewehe maʻalahi no ka mea he nāwaliwali loa ka pane magnetic intrinsic o ka alumini a he mea maʻamau ʻole ia i ke ola o kēlā me kēia lā..

No ka hapa nui o ka ʻenehana, Kālā, a me nā noi hale, ka ʻokoʻa ma waena o ka "paramagnetic nāwaliwali" a me ka "non-magnetic" ʻaʻohe hopena kūpono.

Hoʻohana nui ʻia ka huaʻōlelo no ka mea maʻamau nā hopena i ʻike ʻia e ka poʻe me ka alumini eddy au, ʻaʻole ma ka magnetism ma ke ʻano maʻamau.

I ka hui ʻana o ka alumini me ka neʻe ʻana a i ʻole ka hoʻololi ʻana o ke kahua magnetic, ʻo ka hopena e loaʻa mai ana mai ka hoʻokomo electromagnetic ma mua o ka hoʻohuli manaʻo mau.

ʻO ia ke kumu e hiki ai ke ʻike ʻia ka alumini e "kū'ē" i ka neʻe ʻana i nā hōʻike magnetic ʻoiai ʻaʻole ia he magnetic i ke ala ferromagnetic maʻamau..

I ka pōkole, Ua manaʻo ʻia ʻo alumini he non-magnetic no ka mea ʻaʻole hoihoi nui i nā magnet, ʻAʻole hiki ke hoʻopaʻa i ka magnetization, a ke hana nei ma ke ʻano he metala kuʻuna magnetic i ka hapa nui o nā kūlana honua maoli.

ʻO ka wehewehe ʻepekema ʻoi aku ka pololei ʻo ia paramagnetic nāwaliwali.

5. ʻO ka Physics ma hope o ka Aluminum a me ka Magnetism

ʻO ke ʻano magnetic o Aluminum mai kona hoʻonohonoho electron a me ka hoʻolālā atomika.

Paramagnetism i ka alumini

Loaʻa i nā mea paramagnetic nā electrons i hui ʻole ʻia e hana i nā manawa magnetic liʻiliʻi.

Ke hoʻohana ʻia kahi māla magnetic waho, ua kulike iki ia mau manawa me ke kahua. I ka alumini, nawaliwali loa keia alignment a nalowale ke wehe ia ke kahua.

ʻAʻohe magnetization mau

ʻAʻole like me nā mea ferromagnetic, ʻAʻole i loaʻa i ka alumini nā kāʻei magnetic kūloko ikaika e paʻa i ka alignment. ʻO ia ke kumu ʻaʻole hiki ke lilo i magnet mau.

Eddy au i nā kula neʻe

Eia kahi i lilo ai ka alumini i mea hoihoi loa. ʻOiai ʻaʻole ia he magnetic ikaika, he uila uila.

I ka neʻe ʻana o ka alumini ma waena o kahi māla magnetic, a i ʻole i ka wā e hoʻololi ai ke kahua magnetic a puni, eddy au hoʻokomo ʻia i loko o ka metala.

Hoʻokumu kēia mau au i kā lākou mau māla magnetic kūʻē. Ma ka hopena, hiki ke alumini:

• hoʻolohi i ka neʻe ʻana o nā magnet,
• hana i ke kū'ē i ʻike ʻia i nā ʻōnaehana electromagnetic,
• pane ikaika i nā hoʻonohonoho braking magnetic.

ʻAʻole like kēia me ka ferromagnetic. He hopena induction electromagnetic ia, ʻaʻole he waiwai magnetic mau.

6. Alloying and Processing: E lilo nā Aluminum Alloys i Magnetic?

Laulaha, ʻAʻole lilo nā alumini alumini ma ke ʻano ferromagnetic no ka mea, ua hoʻohuihui ʻia a i hana ʻia paha.

He kumu ke kumu: ʻAʻole ʻo ka alumini he metala ferromagnetic, a me nā mea hoʻohui hoʻohui maʻamau i hoʻohana ʻia i ka alumini metallurgy ʻaʻole i hana maʻamau i ke ʻano o ke kauoha atomic e pono ai no ka ikaika., hoʻokalakupua mau.

No ke aha i hana pinepine ʻole ai ka alloying i ka alumini magnetic

Hoʻoikaika pinepine ʻia nā alumini alumini me nā mea e like me:

• Magnesum

• zinc
• mang kāne
• Lithium

Ua koho ʻia kēia mau mea hoʻohui e hoʻomaikaʻi i ka ikaika, Ke kū'ē neiʻo Corrosionion, whola, a i ʻole ka pane ʻana i ka wela. ʻo lākou ʻaʻole i manaʻo ʻia e hana i ka ferromagnetism.

ʻO nā microstructure i hana ʻia i loko o nā alumini alumini e kākoʻo maʻamau i ka paʻakikī o ka ua, hoʻoikaika paʻa, aiʻole ka hoʻomaʻemaʻe palaoa, ʻaʻole ka hana hoʻopaʻa inoa magnetic.

ʻO ia hoʻi, e ikaika paha ka alloy, ʻoi aku ka paʻakikī, a ʻoi aku paha ka wela, akā ʻaʻole naʻe e loaʻa i ka ʻōnaehana domain magnetic kūloko i koi ʻia no ka ferromagnetism maoli.

I ka wā e ʻike iki ʻia kahi alumini alumini

Aia kekahi mau kumu e ʻike ʻia ai kahi alumini alumini e launa pū me kahi magnet ma mua o ka alumini maʻemaʻe:

Ka hoʻohaumia ʻana

I ka wā o ka hana ʻana a i ʻole ka mīkini, hiki i kahi ʻāpana alumini ke ʻohi i nā ʻōpala liʻiliʻi o ka hao a i ʻole ke kila.

Hiki i kēlā hoʻohaumia ke hoʻolilo i ka ʻāpana me he mea palupalu palupalu, ʻoiai ʻaʻole ʻo ka alumini ponoʻī.

Mākēneki intermetallic particles

Loaʻa i kekahi mau mea hoʻohuihui liʻiliʻi liʻiliʻi liʻiliʻi liʻiliʻi liʻiliʻi i loaʻa kahi pane magnetic nāwaliwali. He mea liʻiliʻi kēia maʻamau a ʻaʻole ia e hana i ka nui o ka alloy magnetic ma ke ʻano kūpono.

Eddy-nā hopena o kēia manawa

Hiki i kahi magnet hoʻoneʻe kokoke i ka alumini ke hana i kahi hopena ʻike ikaika ʻia no ka mea e hoʻohua ai ka alloy conductive i nā au eddy.

Kuhi pinepine ʻia kēia no ka magnetism, akā, ʻo ia nō kahi hanana induction electromagnetic.

Hoʻololi ka hana i ka magnetism?

Hiki ke hoʻololi i ka hana ikaika, hālulu, a me ke kumu kūʻai uila o kahi alumini alumini, akā, ʻaʻole ia e hoʻololi maʻamau i ka huila i mea hoʻokalakupua.

ʻo kahi laʻana:

• ʻO ka hana wela hiki ke hoʻololi i ka hana hoʻoheheʻe a me nā waiwai mechanical.
• Ke hana anuanu hiki ke hoʻololi i ke ʻano o ka palaoa a me ka ikaika.
• Casting vs. hana hana hiki ke hoʻopili i ka puʻupuʻu haumia a me ka like ʻole microstructural.

Hiki i kēia mau hoʻololi ke hoʻololi iki i ka pane ʻana o ka mea i kahi kahua magnetic, akā ʻaʻole lākou e hana i ka ferromagnetism maoli.

Ka hopena hoʻokō

Mai kahi hananaʻenehana, Ua manaʻo ʻia nā alumini alumini nā mea non-magnetic.

Hiki ke hoʻokomo i nā ʻano liʻiliʻi liʻiliʻi i ka pane magnetic, akā, ʻaʻole lākou e hana i ka alumini e like me ka metala magnetic ma ke ʻano maʻamau.

No laila ka hopena kūpono:

ʻAʻole lilo nā alumini alumini i ka magnetic no ka mea ua hoʻohui ʻia a i hana ʻia paha; i ka nui loa, nawaliwali loa lakou, nā hopena magnetik.

7. ʻO nā manaʻo kuhihewa maʻamau a me nā hōʻike maʻamau

kuhi hewa 1: "Inā ʻaʻole pili ka magnet, ʻAʻole magnetic ka mea. "

ʻAʻole loa. ʻAʻole pili ka alumini i kahi magnet, akā naʻe, loaʻa iā ia kahi pane magnetic nāwaliwali a hiki ke launa pū me ka hoʻololi ʻana i nā māla magnetic.

kuhi hewa 2: "Inā hiki i ka alumini ke hoʻopili i nā magnet, he mea magnetic ia.

hou, ʻaʻole pololei. ʻO ka hopena ma muli o ka conductivity a me nā au i hoʻokomo ʻia, ʻaʻole ferromagnetism intrinsic.

kuhi hewa 3: "He magnetic nā metala āpau."

Wahahee. ʻAʻole ikaika loa nā metala he nui. He paramagnetic kekahi, kekahi diamagnetic, a ʻo kahi hui liʻiliʻi wale nō ka ferromagnetic.

Hoʻokolohua maʻalahi

Inā hāʻule ʻoe i kahi magnet ikaika ma o ka paipu alumini, ʻoi aku ka mālie o kona hāʻule ʻana ma mua o ka ea.

ʻO ia ke kumu o ka neʻe ʻana o ka magnet e hoʻoulu i nā au eddy i loko o ka alumini, a ke kū'ē nei kēlā mau au i ka noi.

He hōʻike maʻamau kēia o ka induction electromagnetic, ʻaʻole magnetism maʻamau.

8. Aluminum i loko o nā noi honua maoli

He mea koʻikoʻi ke ʻano maʻemaʻe nāwaliwali o ka alumini ma nā hoʻonohonoho pono.

Aerospace a me ka halihali
