Neodymium Cylinder Magnet N52 – Loaʻa ka laʻana manuahi | Fullzen

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

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

ʻO ka maʻamau, ʻelua mau pou o ka magnet neodymium i ke ʻano o kahi cylinder, he pou ʻākau a he pou hema, e like me nā magnet ʻē aʻe. ʻO nā pou nā kiko ma ka ʻili o ka magnet kahi i ikaika loa ai ke kahua magnetic a puka mai nā laina ikaika magnetic a komo paha i loko o ka magnet.

No ka magnet neodymium cylindrical, aia pinepine ka pou ʻimi ʻākau ma kekahi o nā wēlau pālahalaha, ʻoiai aia ka pou ʻimi hema ma kekahi wēlau pālahalaha. Holo pinepine nā laina kahua magnetic ma ka lōʻihi o ka cylinder, mai ka pou ʻākau a i ka pou hema.

ʻO ka hoʻonohonoho kikoʻī o nā pou a me ke ʻano o ke kahua magnetic e kūlike me nā loina laulā 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 kahi magnet mai kekahi i kekahi; ʻo ka uhaki ʻana i kahi magnet i nā ʻāpana liʻiliʻi e hana wale i nā magnet liʻiliʻi, kēlā me kēia me kā lākou mau pou ʻākau a me hema.

ʻOi aku ka paʻakikī o ke kahua magnetic i hana ʻia e kahi magnet cylindrical mau loa ma mua o kahi formula makemakika maʻalahi ma muli o ke ʻano a me nā waiwai o ka magnet. Eia nō naʻe, hiki ke loaʻa kahi formula kokoke no ke kahua magnetic ma ke axis o kahi magnet cylindrical lōʻihi me ka hoʻohana ʻana i ke kānāwai o Biot-Savart, me ka manaʻo ua magnetized ka magnet ma kona lōʻihi a ua mamao loa ka mea nānā mai nā wēlau o ka magnet:
= 0⋅ 2 ⋅ 2B=2π⋅rμ​⋅M​
Ma hea:
ʻO B ka ikaika o ke kahua magnetic ma kahi mamao r mai ke axis o ka magnet.
ʻO 0μ0 ka permeability o kahi hakahaka (4 ×10−7 T⋅m/A4π×10−7T⋅m/A).
ʻO M ka magnetization o ka mea magnet, e hōʻike ana i ka manawa magnetic no kēlā me kēia anakahi leo (A/mA/m).
Hāʻawi kēia haʻilula i kahi hoʻokokoke ʻana o ka ikaika o ke kahua magnetic ma ke axis o kahi magnet cylindrical lōʻihi. E hoʻomanaʻo e hiki ke hoʻololi ʻia ka hoʻolaha ʻana o ke kahua magnetic maoli e ka lōʻihi o ka magnet, ke anawaena, ke kuhikuhi magnetization, a me nā waiwai kikoʻī o ka mea. No nā helu pololei, ʻoi aku hoʻi no nā magnet me ka magnetization like ʻole a i ʻole nā ​​​​ʻano like ʻole, pono paha nā simulations helu a i ʻole nā ​​​​polokalamu kūikawā.
