ʻO Neodymium Cylinder Magnet N52 - Loaʻa ka Laʻana manuahi | Fullzen

ʻO ka N52 magnet e pili ana i kahi neodymium magnet me ka helu o N52, ʻo ia kekahi o nā māka ikaika loa i loaʻa no nā magnet neodymium. Hōʻike ka "N" he neodymium magnet, a ʻo ka "52" ke hōʻike nei i ka huahana ikehu o ka mea magnet. ʻO ka huahana ikehu kiʻekiʻe ke ʻano o ka magnet ikaika.

Eia nō naʻe, hiki ke ʻokoʻa nā kikoʻī kikoʻī no ka "super ikaika" N52 cylinder magnet ma muli o nā kumu e like me ka nui, ka nui, ka uhi, a me ka mea hana.

ʻO ka neodymium magnet i ke ʻano o ka cylinder maʻamau he ʻelua mau kia, he kia ʻākau a he kia hema, e like me nā mea magnet ʻē aʻe. ʻO nā pole nā ​​kiko ma ka ʻili o ka magnet kahi i ʻoi aku ka ikaika o ka mākēneki a puka mai nā laina mana o ka ikaika a i ʻole ke komo ʻana i ka magnet.

No ka neodymium magnet cylindrical, aia ka pole imi akau ma kekahi o na welau palahalaha, a aia ka pole imi hema ma kekahi welau palahalaha. E holo maʻamau nā laina mākia ma ka lōʻihi o ka pahu, mai ka pole ʻākau a i ka pole hema.

ʻO ka hoʻonohonoho kikoʻī o nā pou a me ke ʻano o ke kahua magnetic e kūlike me nā loina maʻamau o ka magnetism a me nā waiwai o nā magnet mau loa. He mea nui e hoʻomaopopo ʻaʻole hiki ke hoʻokaʻawale ʻia nā pou o ka magnet mai kekahi i kekahi; ʻO ka wāwahi ʻana i ka magnet i ʻāpana liʻiliʻi e hana wale i nā magnet liʻiliʻi, kēlā me kēia me ko lākou mau pou ʻākau a hema.

ʻOi aku ka paʻakikī o ka māla magnetic i hana ʻia e ka cylindrical magnet ma mua o ke kumu makemakika maʻalahi ma muli o ke ʻano a me nā waiwai o ka magnet. Eia naʻe, hiki ke kiʻi ʻia ke kumu hoʻohālikelike no ke kahua mākēneki ma ke koʻi o kahi mākēneki lōʻihi me ka hoʻohana ʻana i ke kānāwai Biot-Savart, me ka manaʻo e hoʻomake ʻia ka magnet ma kona lōʻihi a mamao ka mea nānā mai nā wēlau o ka magnet:
= 0⋅ 2 ⋅ 2B=2π⋅rμ​⋅M​
Ma hea:
ʻO B ka ikaika mākia ma kahi mamao r mai ke axis o ka magnet.
ʻO 0μ0 ʻo ia ka permeability o ke ākea kaʻawale (4 ×10−7 T⋅m/A4π×10−7T⋅m/A).
M ʻo ia ka magnetization o ka mea magnet, e hōʻike ana i ka manawa magnetic no kēlā me kēia leo (A/mA/m).
Hāʻawi kēia ʻano hoʻohālikelike i kahi kokoke o ka ikaika o ke kahua magnetic ma ke koʻi o kahi magnet cylindrical lōʻihi. E hoʻomanaʻo e hiki ke hoʻopili ʻia ka puʻu ʻana o ke kahua magnetic maoli e ka lōʻihi o ka magnet, ke anawaena, ke kuhikuhi magnetization, a me nā waiwai kikoʻī. No ka hoʻohelu pololei ʻana, ʻoi aku ka nui o nā magnet me ka hoʻokalakupua like ʻole a i ʻole nā ​​ʻano ʻano like ʻole, koi ʻia nā hoʻohālikelike helu a i ʻole nā ​​polokalamu kūikawā.
