ʻO ka huila mākēneki Samarium

No nā mākēneki SmCo cylinder magnetized axially magnetized, i kekahi manawa e koi ʻia lākou i nā pou he nui i hoʻopaneʻe ʻia ma ka lōʻihi no kekahi mau noi kikoʻī. Nui nā kumu e hoʻoholo ai inā ua magnetized ka multi poleSmCo magnethiki a ʻaʻole paha, no ka laʻana, koi ʻia ma waena o nā pou magnet, ka nui o ka magnetizing, nā mea magnetizing, nā waiwai magnet, a me nā mea ʻē aʻe.NdFeB magnet. Inā ʻoi aku ka nui o ka SmCo magnet, ʻaʻole hiki i ka mea magnetizer a me ka mea hoʻonaninani ke hoʻohua i ka māla magnetizing e hiki ke hoʻokalakupua iā SmCo i ka saturation. Pono ka mānoanoa o ka mānoanoa SmCo ma lalo o 5 mm, a i kekahi manawa pono e mālama ʻia ka Hcj a puni a ʻaʻole ʻoi aku ma mua o 15kOe. Ma mua o ka hana nui ʻana, pono e hōʻoia ʻia ka laʻana o ka multi-pole magnet e nā hoʻāʻo piha o nā mea kūʻai aku e hoʻokō i nā koi noi.

I kekahi manawa, pono paha e hoʻopaʻa ʻia nā mea hoʻoheheʻe SmCo. ʻAʻole like me ka neodymium magnet sintered maʻalahi e oxidize, maikaʻi ʻo Samarium Cobalt magnet i ka pale ʻana i ka corrosion ma muli o kāna ʻano mea kikoʻī me ka ʻole o Fe a i ʻole ma kahi o 15% hao. No laila i ka nui o nā noi, ʻaʻole pono ka uhi no ka SmCo magnet e pale ai i ka corrosion. Eia nō naʻe, ma kekahi mau kahua noi, koi ʻia ʻo SmCo magnet e uhi ʻia me ke gula ʻālohilohi a nani paha a i ʻole Nickel e hiki ai i kahi hiʻohiʻona kūpono.

Ke hoʻoholo nā mea kūʻai aku i ka mea magnet i kūpono i kā lākou noi, mālama pū lākou i nā waiwai kino. Eia na waiwai kino no SmCo magnets:
