Hollow Cylinder Magnets - Ma ke Kumukuai Haahaa | Fullzen

Hiki ke ʻokoʻa ke kumukūʻai o ka cylinder magnet ma muli o kekahi mau kumu:

1. Mea a me ka Papa
2. Nui a me nā Ana
3. Ka uhi ʻana
4. Ka nui
5. Mea hoolako a me Brand
6. Hoʻopilikino

E ʻoluʻolu, hiki ke loli nā kumukūʻai i ka manawa ma muli o nā kumu e like me ka loli o ka mākeke, hoʻololi i ka lako a me ke koi, a me nā holomua i nā kaʻina hana. No ka loaʻa ʻana o ke kumukūʻai kūpono a me ka manawa hou no ka magnet cylinder kikoʻī āu e makemake ai, manaʻo wau e nānā me nā mea hoʻolako magnet, nā mea hana, a i ʻole nā ​​​​mea kūʻai pūnaewele.

ʻO ke kuʻi magnetic (
$\Phi$

Φ) ma o ka ʻili i hāʻawi ʻia e ke kumu:

$\Phi =�\cdot �\cdot cos(�)$

Φ=B⋅A⋅cos(θ)

ma hea:

• 
  $�$

  ʻO B ka ikaika o ke kahua magnetic (i ka teslas, T).

• 
  $�$

  ʻO A ka ʻāpana o ka ʻili e kū pono ana i ke kahua mākēneki (ma nā mika square, m²).

• 
  $�$

  ʻO θ ka huina ma waena o nā laina mākia a me ka vector maʻamau i ka ʻili.

No ka mea magnet cylindrical, ʻoi aku ka paʻakikī o ke kūlana no ka mea ʻaʻole mau ke kahua magnetic ma luna o ka ʻili holoʻokoʻa ma muli o nā ʻano like ʻole o ka magnetization i loko o ka cylinder. Ma ia mau hihia, pono ʻoe e noʻonoʻo i ka hoʻohui ʻana o ke kahua magnetic ma luna o ka ʻili e helu pono i ka flux magnetic.

Inā ʻano like ʻole ke kahua magnetic a kau ʻia me ke koʻi o ka cylinder, hiki iā ʻoe ke maʻalahi i ke kūlana a hoʻohana i ke ʻano i ʻōlelo ʻia ma luna. Eia nō naʻe, inā e pili ana ʻoe i kahi puʻupuʻu paʻakikī paʻakikī, pono paha ʻoe e hana me nā manaʻo ʻoi aku ka holomua, e like me ka hoʻohui ʻana i ka vector field magnetic ma luna o ka ʻili.

SʻAʻole hoʻohana maʻamau ʻia ka ilver ma ke ʻano he mea e hana ai i nā magnet mau loa, me nā magnet cylinder. Hana ʻia nā mākēneki mau, e like me nā neodymium magnets (NdFeB), mai nā alloys i loaʻa nā mea e like me neodymium, hao, a me ka boron. Loaʻa i kēia mau mea nā hana crystalline kikoʻī e kōkua i ko lākou mau waiwai magnetic ikaika.
