Cylinder Neodymium Magnet 6*13mm – Yemahara Sample Inowanikwa | Fullzen

Kuverenga simba remagineti (
$�$

B) kutenderedza magineti ane silinda kunogona kuoma, zvichienderana nekugoverwa kwemagnetization mukati mesirinda. Pano, ndichatsanangura nyaya iri nyore apo tine sirinda ine magineti yakafanana ine magnetization axis yayo yakabatana ne axis yesirinda. Izvi zvinowanzonzi "sirinda ine magineti yakareba."

Iyo magnetic field (
$�$

B) kunze kwe cylinder ine magineti yakafanana pamwe chete nepakati payo inogona kufungidzirwa uchishandisa fomura yemunda uri mukati me solenoid. Iyi fungidziro inofungidzira kuti cylinder yakareba kupfuura dhayamita yayo. Fomura yacho ndeiyi:

$�=�\cdot �$

B=μ⋅M

Kupi:

• 
  $�$

  B isimba remagineti pane imwe nzvimbo iri kunze kwecylinder (mu teslas, T).

• 
  $�$

  μ ndiyo kupenya kwezvinhu (nguva dzose, kazhinji
  $�0$

  μ0 yevacuum kana mweya, yakaenzana ne
  $4�\times 10-7$

  4π×10−7 T m/A).

• 
  $�$

  M ndiyo magnetization ye cylinder (magnetic moment per unit volume, muA/m).

Kune silinda ine magineti yakafanana,
$�$

M inogona kuverengerwa se:

$�=�huremu\; hwachose�$

M=Vsilinda​Mtotal​

Kupi:

• 
  $�huwandu$

  Mtotal ndiyo yakazara magineti nguva yecylinder (muA m²).

• 
  $�Sirinda$

  Vcylinder ndiyo ivhu rehumburumbira (mu m³).

Rangarirai kuti iyi inyaya iri nyore uye ingasaratidza kugoverwa kwesimba remagineti nenzira chaiyo mune dzimwe nyaya dzakaoma. Kana magnetization isina kufanana, kana kuti saizi yesilinda isina kukura zvakanyanya kupfuura dhayamita yayo, kuverenga kwacho kunova kwakaoma uye kunogona kuda matekiniki ekuverenga kana ekuongorora.

Kuti uwane mamwe mhedzisiro mhedzisiro, ungangoda kushandisa nzira dzepamberi senge manhamba ekufungidzira uchishandisa inogumira chinhu chekuongorora kana nzira dzekuongorora dzinofunga nezvemagineti zvimiro zvechinyorwa uye kugovera chaiko magineti mukati me silinda.

Chirevo chekuti magineti i zero mukati mehumburumbira inogona kunge iri kusanzwisisa kana kuwedzeredza. Kazhinji, iyo magineti mukati meinofanana magnetized cylinder haisi zero. Nekudaro, zvichienderana nemamiriro chaiwo uye fungidziro, pane zviitiko apo iyo magineti mukati me cylinder inogona kuve isina kusimba kana kuratidza zvimwe zvivakwa zvingaita kuti zviite senge munda haukodzeri.

Heano maitiro akati wandei anogona kutungamira kune pfungwa yekuti iyo magineti ndeye zero mukati me silinda:

1. Shielding
2. Uniform Magnetization

Zvakakosha kuziva kuti simba remagineti riri mukati memagineti ane cylindrical rinotsamira pazvinhu zvakasiyana-siyana, kusanganisira kugoverwa kwesimba remagineti, chimiro chemagineti, hunhu hwezvinhu, uye zvinopesvedzera zvekunze zvakaita sesimba remagineti riri pedyo kana kudzivirira. Kazhinji, simba resimba remagineti rinogona kuverengerwa uye kutevedzera zvichibva pazvinhu izvi, asi simba racho haringaite kunge riri zero chaiyo mukati mesilinda ine simba remagineti rakafanana.

Hongu, panogona kunge paine magineti mukati mehumburumbira, chero iyo silinda ine imwe nzira yemagnetization. Kuvapo uye hunhu hwesimba remagineti mukati megomba silinda zvinoenderana nezvinhu zvakaita semagineti patani, zvinhu zvemukati, uye geometry yecylinder.

Simba remagineti riri mukati nekunze kwegineti rinotenderera zvinoenderana nezvinhu zvakasiyana-siyana, kusanganisira maitiro emagnetization, hunhu hwezvinhu, uye geometry yegineti. Ngatifungei nezvezviitiko zvishoma:

1. Uniformly Magnetized Cylinder
2. Sirinda ine Magneti Yakanyanya
3. Sirinda Yakabviswa Magineti Yakakora
4. Magnetic Shielding Cylinder

Idzi tsananguro dzakareruka, uye maitiro chaiwo eiyo magineti anogona kunge akaomarara zvichienderana nemamiriro chaiwo uye fungidziro. Mukuita, iyo magineti kugovera kunowanzo kuongororwa uchishandisa masvomhu modhi kana simulation software iyo inofunga nezve yakadzama hunhu hwemagineti nenzvimbo yayo.
