Hoʻomaka ka Neodymium Magnets? E aʻo e pili ana i nā Mākēneki NdFeB

Neodymium magnets, i ʻike ʻia ʻoNdFeB magnet, aia ma waena o nāmau magnet ikaika loaloaʻa. Hoʻokumu mua ʻia me ka neodymium, hao, a me ka boron, ua hoʻololi kēia mau mea magnet i nā ʻoihana like ʻole ma muli o ko lākou ikaika magnetic a me ka versatility. Eia nō naʻe, kū mai kahi nīnau maʻamau: Ua hana nā neodymium magnets i nā huna huna? No ka pane ʻana i kēia nīnau, pono mākou e ʻimi hohonu i nā waiwai o kēia mau meamagnets a me nā kūlana e hiki mai ai nā ʻulaʻula.

Nā waiwai o nā Mākēneki Neodymium

ʻO nā magnet Neodymium no nā mea magnet honua i ʻike ʻia no ko lākou mau waiwai magnetic. ʻOi aku ka ikaika o lākou ma mua o nā magnet maʻamau, e like me ka ceramic a i ʻole alnico magnets, e hoʻolilo iā lākou i mea kūpono no nā noi mai nā mīkini uila a i nā mīkini hoʻohālikelike magnetic (MRI). Loaʻa i nā mea magnet NdFeB ko lākou ikaika i ko lākou ʻano aniani kū hoʻokahi, kahi e hiki ai ke kiʻekiʻe kiʻekiʻe o ka ikehu magnetic.

Hiki i nā neodymium magnets ke hana i nā huna huna?

I ka pōkole, ʻaʻole e hoʻopuka nā neodymium magnets iā lākou iho. Eia nō naʻe, hiki mai nā ʻōlinolino ma lalo o kekahi mau kūlana, ʻoi aku ka nui o ka hoʻohana ʻia ʻana o kēia mau magnet me nā mea conductive a i ʻole i kekahi mau noi mechanical.

1. Ka hopena Mechanical: I ka hui ʻana o ʻelua neodymium magnets me ka ikaika nui, hiki iā lākou ke hana i nā huna huna ma muli o ka neʻe wikiwiki a me ka hakakā ma waena o nā ʻili. Hiki paha kēia inā nui a kaumaha nā magnet, no ka mea, hiki ke nui ka ikehu kinetic i loko o ka hopena. ʻAʻole ʻo nā ʻōlinolino he hopena o nā waiwai magnetic o ka magnet, akā ʻo ka pilina kino ma waena o nā magnet.

2. Nā Hana Uila: Ma nā noi kahi e hoʻohana ʻia ai nā magnet neodymium i nā kaʻa a i ʻole nā ​​mea hoʻoheheʻe, hiki ke puka mai nā ʻōlinolino mai nā pulupulu a i ʻole nā ​​​​pili. ʻAʻole kēia ma muli o nā magnets ponoʻī, akā no ka hele ʻana i kēia manawa ma o nā mea conductive. Inā he ʻāpana nā mea magnet o kahi ʻōnaehana i hana ʻia ai ka arcing, e hiki mai ana nā huna huna, akā he pilikia kēia i pili ʻole i nā waiwai magnetic o ka magnet.

3. Demagnetization: Inā loaʻa ka neodymium magnet i ka wela nui a i ʻole ke koʻikoʻi kino, e nalowale ana kona mau waiwai. I kekahi mau hihia, hiki i kēia demagnetization ke hopena i ka hoʻokuʻu ʻana o ka ikehu i ʻike ʻia e like me nā ʻālohilohi akā ʻaʻole ia he hopena pololei o nā waiwai inherent o ka magnet.

Palapala Palekana

ʻOiai palekana nā neodymium magnets i ka hapa nui o nā noi, pono e mālama ʻia me ka mālama. Hiki i ko lākou māla ikaika ke hōʻeha inā hopu ʻia nā manamana lima a i ʻole nā ​​​​ʻāpana kino ʻē aʻe ma waena o nā magnet. Eia kekahi, i ka wā e hana ai me nā magnet neodymium nui, pono e makaʻala kekahi i ka hiki ke loaʻa i ka hopena mechanical e hiki ai ke hoʻoulu i nā pua.

Ma nā wahi i loaʻa nā mea puhi ahi, ʻoi aku ka maikaʻi e pale aku i nā kūlana kahi e hoʻokuʻi ʻia ai nā magnet. Pono e mālama i nā hana palekana kūpono i ka wā e lawelawe ana i nā magnet ikaika.
