Cylinder Neodymium Magnet 6 * 13mm - Zitsanzo Zaulere Zilipo | Fullzen

Kuwerengera mphamvu ya maginito (
$�$

B) kuzungulira cylindrical maginito kungakhale kovuta kwambiri, kutengera kugawa kwa maginito mkati mwa silinda. Apa, ndifotokoza nkhani yophweka pomwe tili ndi silinda yofanana ndi maginito yokhala ndi nsonga yake yamagetsi yolumikizidwa ndi axis ya silinda. Izi nthawi zambiri zimatchedwa "longitudinally magnetized cylinder."

Mphamvu ya maginito (
$�$

B) kunja kwa silinda yofanana ndi maginito yomwe ili m'mbali mwake yapakati imatha kuyerekezedwa pogwiritsa ntchito chilinganizo chamunda mkati mwa solenoid. Kuyerekeza uku kumaganiza kuti silinda ndi yayitali kwambiri kuposa mainchesi ake. Fomula ndi:

$�=�\cdot �$

B=μ⋅M

Kumene:

• 
  $�$

  B ndiye mphamvu ya maginito yomwe ili kunja kwa silinda (mu teslas, T).

• 
  $�$

  μ ndikuthekera kwazinthu (zokhazikika, nthawi zambiri
  $�0$

  μ0 ​ ya vacuum kapena mpweya, wofanana ndi
  $4\times 10-7$

  4π×10−7 T m/A).

• 
  $�$

  M ndi maginito a silinda (maginito mphindi pa voliyumu unit, mu A/m).

Kwa silinda yofanana ndi maginito,
$�$

M ikhoza kuwerengedwa motere:

$�=�chilinda\; chathunthu$

M=Vcylinder Mtotal

Kumene:

• 
  $�\; chonse$

  Mtotal ndiye mphindi yonse ya maginito ya silinda (mu A m²).

• 
  $�cylinder$

  Vcylinder ndi kuchuluka kwa silinda (mu m³).

Kumbukirani kuti ichi ndi chithunzi chosavuta ndipo sichingawonetse molondola kugawa kwa maginito muzochitika zovuta kwambiri. Ngati maginito sali ofanana, kapena ngati miyeso ya silinda siikulu kwambiri kuposa m'mimba mwake, kuwerengera kumakhala kovuta kwambiri ndipo kungafunike njira zowerengera kapena zowunikira.

Kuti mupeze zotsatira zolondola, mungafunike kugwiritsa ntchito njira zapamwamba monga kuyerekezera manambala pogwiritsa ntchito kusanthula komaliza kapena njira zowunikira zomwe zimaganizira momwe maginito amagwirira ntchito komanso kugawa kwenikweni kwa maginito mkati mwa silinda.

Mawu akuti mphamvu ya maginito ndi ziro mkati mwa silinda ikhoza kukhala kusamvetsetsana kapena kuphweka. Nthawi zambiri, mphamvu ya maginito mkati mwa silinda yofanana ndi maginito si ziro. Komabe, malingana ndi mikhalidwe yeniyeni ndi malingaliro, pali zochitika pamene mphamvu ya maginito mkati mwa silinda ikhoza kukhala yofooka kapena kusonyeza zinthu zina zomwe zingapangitse kuti ziwoneke ngati malowa ndi osafunika.

Nazi zochitika zingapo zomwe zingayambitse kuganiza kuti mphamvu ya maginito ndi zero mkati mwa silinda:

1. Kuteteza
2. Uniform Magnetization

Ndikofunika kuzindikira kuti mphamvu ya maginito mkati mwa cylindrical maginito idzadalira zinthu zosiyanasiyana, kuphatikizapo kugawa kwa magnetization, mawonekedwe a maginito, katundu wakuthupi, ndi zochitika zakunja monga maginito oyandikana nawo kapena chitetezo. Nthawi zambiri, mphamvu ya maginito imatha kuwerengeka ndikufaniziridwa potengera izi, koma gawolo silingafanane ndi zero mkati mwa silinda yofanana ndi maginito.

Inde, pakhoza kukhala mphamvu ya maginito mkati mwa silinda yopanda kanthu, malinga ngati silindayo ili ndi mtundu wina wa maginito. Kukhalapo ndi mawonekedwe a mphamvu ya maginito mkati mwa silinda yopanda kanthu kumadalira zinthu monga magnetization pattern, katundu, ndi geometry ya silinda.

Mphamvu ya maginito mkati ndi kunja kwa cylindrical maginito zimatengera zinthu zosiyanasiyana, kuphatikiza mawonekedwe a magnetization, zinthu zakuthupi, ndi geometry ya silinda. Tiyeni tione zochitika zingapo:

1. Uniformly Magnetized Cylinder
2. Radially Magnetized Cylinder
3. Demagnetized Hollow Cylinder
4. Magnetic Shielding Cylinder

Awa ndi mafotokozedwe osavuta, ndipo machitidwe enieni a maginito amatha kukhala ovuta kutengera momwe zinthu ziliri komanso malingaliro ake. M'zochita, kugawa kwa maginito kumawunikidwa nthawi zambiri pogwiritsa ntchito masamu kapena mapulogalamu oyerekeza omwe amaganizira zatsatanetsatane wa maginito ndi chilengedwe chake.
