Hoʻonā no ka demagnetization wela kiʻekiʻe o NdFeb

ʻO nā hoaaloha i loaʻa kekahi ʻike i nā mea magneti, ʻike lākou i kēlāNdFeb Neodymium Magnetʻike ʻia ma ke ʻano he hana kiʻekiʻe a me ke kumu kūʻai o nā huahana magnet i loko o ka ʻoihana mea magnetic i kēia manawa.Nui nā ʻenehana kiʻekiʻe i koho ʻia e hana i nā ʻāpana like ʻole, e like me ka pūʻali koa pale aupuni, ka ʻenehana uila, nā mea lapaʻau, nā lako uila a me nā māla ʻē aʻe e pili ana. ua hoʻokipa nui ka ʻāina wela kiʻekiʻe. 

No ke ahaNdFeb Mākēneki maudegenerate i ka wela kiʻekiʻe?

NdFeb degaussing ma ke kiʻekiʻe wela ua hoʻoholo 'ia e kona physical structure.The magnetic field hiki ke hanaia e ka magnet, no ka mea, o na electrons i laweia e ka mea huli a puni ka atom ma kekahi kuhikuhi, e hoopuka i kekahi mana magnetic, a laila, he hopena. ma nā mea pili a puni.Akā, nā electrons a puni nā ʻātoma e like me ke kuhikuhi i hoʻokumu ʻia i kekahi mau kūlana wela, ʻokoʻa ka mea magnetik hiki ke kū i ka mahana he ʻokoʻa, i ka hihia o ka wela kiʻekiʻe, e haʻalele ka uila mai ke ala kumu. chaotic hanana, mea magnetic i kēia manawa e huhū ke kahua magnetic kūloko, a me ka demagnetization.

Eia nō naʻe, ʻo ka pale wela o nā magnet NdFeb ma kahi o baidu, ʻo ia hoʻi, ʻoi aku ka nui o ka baidu e ʻike ʻia ka demagnetization phenomenon, inā ʻoi aku ka nui o ka mahana, ʻoi aku ka koʻikoʻi o ka demagnetization.

Nui nā hopena kūpono i ka demagnetization wela kiʻekiʻe o NdFeb, hōʻike ʻia nā magnet.

ʻO ka mea mua, mai hoʻokomo i ka huahana NdFeb magnet i ke kiʻekiʻe kiʻekiʻe, e hoʻolohe pono i kona wela koʻikoʻi, ʻo ia hoʻi ʻo baidu, e hoʻoponopono pono i ka mahana o ke kaiapuni hana, i mea e hōʻemi ai i ka hiki ʻana o ka demagnetization.

ʻO ka lua, ʻo ia ka hoʻomaikaʻi ʻana i ka hana o nā huahana me ka hoʻohana ʻana i nā magnet NdFeb mai ka ʻike loea, i hiki iā lākou ke loaʻa i kahi hoʻolālā wela a ʻaʻole hiki ke hoʻopilikia ʻia e ke kaiapuni. 

ʻO ke kolu, hiki iā ʻoe ke koho i nā mea ikaika kiʻekiʻe me ka hoʻonui ʻana i ka ikehu like.Inā ʻaʻole, pono ʻoe e mōhai aku i kahi hōʻiliʻili liʻiliʻi o ka ikehu, a loaʻa nā mea me ka haʻahaʻa haʻahaʻa o ka ikehu a me ka ikaika coercive kiʻekiʻe, akā ʻaʻole hou, hiki iā ʻoe ke koho i ka samarium cobalt;no ka reversible demagnetization, walekobalt samariumloaʻa.
