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

Kuwerengera mphamvu ya maginito (
$�$

B) kuzungulira maginito ozungulira kungakhale kovuta kwambiri, kutengera kugawa kwa maginito mkati mwa silinda. Pano, ndifotokoza nkhani yosavuta pomwe tili ndi silinda yolumikizidwa mofanana ndi mzere wake wa maginito womwe umagwirizana ndi mzere wa silinda. Izi nthawi zambiri zimatchedwa "silinda yolumikizidwa ndi maginito nthawi yayitali."

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 magnetization ya silinda (mphindi ya maginito pa voliyumu ya unit, mu A/m).

Kwa silinda yofanana ndi maginito,
$�$

M ikhoza kuwerengedwa motere:

$�=�chonse�silinda$

M=Vsilinda​Mtotal​

Kumene:

• 
  $�zonse$

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

• 
  $�cylinder$

  Vcylinder ndi kuchuluka kwa silinda (mu m³).

Kumbukirani kuti ichi ndi chithunzi chosavuta ndipo sichingaimirire 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. Magnetization Yofanana

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, bola ngati silindayo ili ndi mtundu wina wa maginito. Kupezeka ndi makhalidwe a mphamvu ya maginito mkati mwa silinda yopanda kanthu kumadalira zinthu monga mawonekedwe a maginito, mawonekedwe a zinthu, ndi mawonekedwe a silindayo.

Mphamvu ya maginito mkati ndi kunja kwa maginito ozungulira imadalira zinthu zosiyanasiyana, kuphatikizapo kapangidwe ka maginito, mawonekedwe a zinthu, ndi mawonekedwe a silinda. Tiyeni tikambirane zochitika zingapo:

1. Silinda Yokhala ndi Maginito Yofanana
2. Radially Magnetized Cylinder
3. Silinda Yopanda Magneti Yopanda Magneti
4. Silinda Yoteteza Maginito

Izi ndi mafotokozedwe osavuta, ndipo khalidwe lenileni la mphamvu ya maginito likhoza kukhala lovuta kwambiri kutengera mikhalidwe ndi malingaliro enieni. Mwachizolowezi, kugawa mphamvu ya maginito nthawi zambiri kumasanthulidwa pogwiritsa ntchito zitsanzo zamasamu kapena mapulogalamu oyeserera omwe amaganizira za mawonekedwe a maginito ndi malo ake.
