He aha ka neodymium magnet?

Loaʻa i kahi neodymium magnet (neomagnet) ka neodymium, ka hao a me ka boron ma waena o nā mea ʻē aʻe. ʻO kēia ka magnet ikaika loa ma ka mākeke.  Ua loaʻa nā mea magnet Neodymium Ferroboron (NdFeB) i ka lehulehu ma 1984 ma hope o ka hoʻomohala ʻia ʻana i kekahi mau makahiki ma mua.

ʻO nā pōmaikaʻi o nā magnet neodymium

• ʻO ia ka magnet paʻa ikaika loa i ke ola. ʻO nā neodymium liʻiliʻi liʻiliʻi i loaʻa ka ikaika magnetic a hiki ke hāpai i nā ukana a hiki i 1000 mau manawa i ko lākou kaumaha ponoʻī.
• Kūleʻa nui lākou i ka demagnetization.
• ʻO nā neomagnets liʻiliʻi he ikaika kiʻekiʻe.
• He kumukuai haahaa loa ko lakou.

  

ʻO nā hemahema o nā magnet neodymium

• ʻO nā magnet Neodymium he mea ʻino loa a pono e mālama pono. No ka hana ʻana i kēia, ua uhi ʻia lākou no ka hana kiʻekiʻe.

He aha nā neodymium magnets i uhi ʻia me?

Hoʻopili ʻia nā magnet Neodymium e pale i ka corrosion no ka mea he 75% hao. ʻO ka uhi maʻamau no nā magnet neodymium he nickel-copper-nickel, ʻoiai ʻoi aku ka nui o nā uhi ʻē aʻe.

ʻO ka uhi ʻana e pale i ka magnet mai nā ʻano wai like ʻole, akā naʻe, inā ʻoki a haki ʻia ka uhi, ʻaʻole ia e pale hou i ka magnet.
