Cov Hlau Nplaum Hollow Cylinder - Tus Nqi Qis | Fullzen

Tus nqi ntawm lub cylinder magnet tuaj yeem sib txawv ntau nyob ntawm ntau yam:

1. Khoom siv thiab qib
2. Qhov Loj thiab Qhov Ntev
3. Txheej
4. Ntau
5. Tus Neeg Muag Khoom thiab Hom
6. Kev kho kom haum

Thov nco ntsoov tias cov nqi tuaj yeem hloov pauv raws sijhawm los ntawm cov yam ntxwv xws li kev hloov pauv ntawm kev lag luam, kev hloov pauv ntawm cov khoom siv thiab kev xav tau, thiab kev nce qib hauv kev tsim khoom. Yuav kom tau txais tus nqi raug thiab hloov tshiab rau cov khoom tshwj xeeb lub tog raj kheej hlau nplaum uas koj xav tau, kuv xav kom kuaj xyuas nrog cov khoom siv hlau nplaum, cov tuam txhab, lossis cov khw muag khoom hauv online.

Lub zog sib nqus (
$\Phi$

Φ) los ntawm ib qho chaw yog muab los ntawm cov mis:

$\Phi =�\cdot �\cdot cos(�)$

Φ=B⋅A⋅cos(θ)

qhov twg:

• 
  $�$

  B yog lub zog ntawm lub zog sib nqus (hauv teslas, T).

• 
  $�$

  A yog thaj tsam ntawm qhov chaw perpendicular mus rau magnetic teb (hauv square meters, m²).

• 
  $�$

  θ yog lub kaum sab xis ntawm cov kab sib nqus thiab lub vector ib txwm mus rau qhov chaw.

Rau ib lub hlau nplaum cylindrical, qhov xwm txheej yuav nyuaj me ntsis vim tias lub zog sib nqus tsis tas li thoob plaws qhov chaw vim muaj kev hloov pauv ntawm kev sib nqus hauv lub tog raj kheej. Hauv cov xwm txheej zoo li no, koj yuav tsum xav txog qhov sib xyaw ntawm lub zog sib nqus hla qhov chaw kom suav qhov sib nqus flux kom raug.

Yog hais tias lub magnetic teb yog sib xws thiab ua raws li cov axis ntawm lub tog raj kheej, tej zaum koj yuav ua tau yooj yim qhov teeb meem no thiab siv cov mis uas tau hais los saum no. Txawm li cas los xij, yog tias koj tab tom cuam tshuam nrog kev sib nqus sib nqus ntau dua, koj yuav tsum tau ua haujlwm nrog ntau lub tswv yim, xws li kev sib koom ua ke ntawm magnetic teb vector saum npoo.

Silver feem ntau tsis yog siv los ua cov khoom siv los ua cov hlau nplaum ruaj khov, suav nrog cov hlau nplaum lub tog raj kheej. Cov hlau nplaum tas mus li, xws li cov hlau nplaum neodymium (NdFeB), feem ntau yog tsim los ntawm cov hlau nplaum uas muaj cov khoom xws li neodymium, hlau, thiab boron. Cov ntaub ntawv no muaj cov qauv crystalline tshwj xeeb uas ua rau lawv cov khoom sib nqus muaj zog.
