Hoʻohālikelike Hana Ma waena o nā Magnets Channel Neodymium a me nā ʻAno Magnet ʻē aʻe

ʻO ka "Superhero" o nā Magnets: No ke aha ʻo Arc NdFeBNā Mākēneki KahawaiMana Loa?

Aloha kākou! I kēia lā, e kamaʻilio kākou e pili ana i nā magnet - ʻo kēia mau mea liʻiliʻi maʻamau akā hoihoi. Ua ʻike anei ʻoe? ʻO ka ʻokoʻa ma waena o nā magnet like ʻole e like me ka nui o nā mea ma waena o nā kelepona akamai a me nā kelepona paʻalima maʻamau! ʻOi loa aku nā magnet kahawai NdFeB (Neodymium Iron Boron) i kaulana i kēia mau lā - ʻo lākou ke "Iron Man" o ka honua magnet. No laila, pehea lākou i ka kupaianaha? He aha ka mea e hoʻokaʻawale ai iā lākou mai nā magnet ʻē aʻe? Mai hopohopo, e wehewehe mākou i kēlā me kēia ʻanuʻu.

 

1. E hui me ka ʻOhana Magnet

ʻO ka mea mua, e hoʻolauna kākou i nā "ʻohana nui ʻehā" o nā magnet:

Nā Mākēneki NdFeB - ʻO nā "mea hoʻokō kiʻekiʻe" o nā mākēneki

ʻO nā magnet paʻa ikaika loa ma ka honua i kēia manawa

Hana ʻia me ka neodymium, ka hao, a me ka boron

E like me nā "bodybuilders" o nā magnets - ikaika loa akā he ʻano wela iki

Nā Mākēneki Ferrite - ʻO nā "lio hana"

 

Koho hoʻokele waiwai loa

Hana ʻia mai ka hao oxide a me nā hui strontium/barium

Kū'ē maika'i loa i ka pala akā nāwaliwali ka ikaika magnetic

Nā Mākēneki AlNiCo - ʻO nā "koa kahiko"

ʻO kekahi o nā mea magnet mau loa kahiko loa

Paʻa mahana koʻikoʻi

E like me nā mea pāʻani evergreen me nā hiki anti-demagnetization ikaika

Nā Mākēneki SmCo - ʻO nā "elite hanohano"

 

ʻO kekahi magnet honua laha hana kiʻekiʻe

Kūpaʻa i ka wela a pale i ka popo

ʻOi aku ke kumukūʻai ma mua o NdFeB, e lawelawe ana i nā noi premium

 

2. Nā Mana Nui o nā Mākēneki Kahawai NdFeB

 

No ke aha i kapa ʻia ai lākou ʻo "Iron Man"? No ka mea, he mau hiki kupaianaha ko lākou:

 

Ka ikaika Magnetic like ʻole

10 manawa ʻoi aku ka ikaika ma mua o nā magnet ferrite! (E noʻonoʻo i kahi mea hāpai kaumaha vs. kahi haumāna kula haʻahaʻa)

Hiki i ka Remanence ke hōʻea i ka 1.0-1.4 Tesla (hiki i nā magnet maʻamau ke loaʻa i ka 0.2-0.4 wale nō)

Ka hiki ke pale aku i ka demagnetization, e like me ka iʻa hiki ʻole ke luku ʻia

 

Hoʻolālā Kahawai Akamai

ʻO ka hoʻolālā Groove e hiki ai i ka mana pololei o ke kahua magnetic, e like me ka hāʻawi ʻana i ka magnetism GPS hoʻokele

ʻOi aku ka paʻa o ke ʻano, ʻaʻole i maʻalahi i nā "haki"

Maʻalahi e hoʻouka, e like me ka hōʻuluʻulu ʻana i nā poloka Lego

 

Ke Aliʻi o ka Hana Kumukūʻai

ʻOiai ke kiʻekiʻe o ke kumukūʻai o kēlā me kēia ʻāpana ma mua o ka ferrite, hāʻawi ia i ke kumukūʻai haʻahaʻa loa no kēlā me kēia ʻāpana magnetic

Hoʻokō i ka magnetism ikaika me ka liʻiliʻi o ka nui, e mālama ana i ka wahi a me ke kālā

 

3I ka manawa hea e koho ai i ka "Superhero" hea?

 

E koho i nā Magnets NdFeB Channel i ka wā:

Ua kaupalena ʻia ka wahi akā pono ka magnetism ikaika (e like me nā pepeiao pepeiao uea ʻole, nā mīkini haʻalulu kelepona)

Pono ka mana o ke kahua magnetic pololei (e laʻa, nā mea hoʻōla magnetic, nā mea ʻike)

Neʻe pinepine ʻana (e laʻa, nā motika EV, nā motika drone)

ʻO ka hoʻolālā māmā ka mea nui (nā lako aerospace)

 

E koho i nā magnet ʻē aʻe i ka wā:

Nā wahi wela loa (ma luna o 200°C)

Nā kūlana ʻino loa (nā lako kahakai)

Ka hoʻolālā kālā paʻa no ka hana nui ʻana

Nā mea hana i maʻalahi loa i nā loli o ka mahana

 

4Nā Manaʻo no ka Hoʻohana ʻana i nā Mākēneki NdFeB

 

E hāʻawi iā lākou i "lole":ʻO ka uhi ʻili (nickel, zinc, a i ʻole epoxy) no ka pale ʻana i ka popo

He "puʻuwai aniani" lākou:E lawelawe me ke akahele i ka wā e hoʻokomo ai - he palupalu lākou

ʻIke i ka wela:Hiki i nā mahana kiʻekiʻe ke hoʻoulu i ka "nalowale ʻiʻo" mau loa (demagnetization)

He mea nui ke kuhikuhiPono e hoʻopili ʻia e like me ke kuhikuhi hoʻolālā

E lawelawe me ke akahele:Hiki i nā kahua magnetic ikaika ke hoʻopilikia i nā kāleka hōʻaiʻē, nā uaki; e mālama mamao mai nā mea hoʻohana pacemaker

 

5He aha ka mea e hiki mai ana?

 

Nā mana ikaika aʻe:Ke hoʻomohala nei nā kānaka ʻepekema i nā māka hou ikaika aʻe

ʻOi aku ka pale wela:Ke hoʻemi nei iā lākou i ka ʻike i nā mahana kiʻekiʻe

Nā hoʻolālā akamai:Ke hoʻohana nei i nā kamepiula e hoʻomaikaʻi i nā ʻano kahawai

Nā hoʻonā ʻōmaʻomaʻo: Hoʻomaikaʻi i ka ʻenehana hana hou, e hōʻemi ana i ka hoʻohana ʻana i ka honua laha ʻole

ʻOi aku ke kumukūʻai kūpono: Hoʻonui i ka hana ʻana e hoʻohaʻahaʻa i nā kumukūʻai

 

Nā Manaʻo Hope Loa

Ua like nā mākēneki kahawai NdFeB me nā "poʻokela a puni" o ka honua magnet, ke koho mua no ka hapa nui o nā noi ʻenehana kiʻekiʻe. Akā, ʻaʻole lākou mana loa - e like me kāu e hoʻohana ʻole ai i kahi kaʻa haʻuki e huki i nā waiwai, ʻo ke kī ke koho ʻana i ka mea hana kūpono no ka hana.
