Induction magnetic

Waxaan ognahay in kaari hadda-sidday lagu meeleeyay beer magnetic, waxaa la hoos geliyey ciidan. Its jihada ku xiran tahay jihada of khadadka duurka, iyo jihada of hadda: haddii dambaysta ah waxaa lagu yaqaan, dhinaca ciidamada la go'aamin karaa by isticmaalaya xeerka bidix ama midig fur.

War haatan aynu ka fiirso wixii ay go'aamiso qiimaha ciidanka this. Iyadoo lagu tilmaamayo in ay waayo-aragnimo ah.

Hakinta ee garabka bidix ee rookaha ah lever qolfo kaari toosan AB iyo meel u dhaxaysa ulihiina N iyo S of electromagnet si ay dadab waa marka la eego khadadka magnetic field. Si joogto ah la guide waxay ka koobnaan doontaa ammeter iyo rheostat, oo aad ku qiyaastaan ayaa karo hadda ee kaari this. Dheelli dulmiga, iyo Bannaankii waa xiran yihiin. Ha haatan ee kaari AB ka B u soo diray inuu A. miisaanka The dheelitirka jabay; si ay u soo celiyaan, on koob sax ah waxay yeelan doonaan in ay ku riday raznovesok dheeraad ah oo miisaankiisu waa loo siman yahay si ay ciidamada balaaran on silig vertical hoos. Waxaan u beddeli doontaa hadda haatan kaari; waxaan la soco in kordhay hadda la kordhay iyo ciidanka in u dhaqmo on gaariga. Isbedelada na tusi doonaa in ciidamada oo duurka ku magnetic u dhaqmo on kaari waa si toos ah saamiyeed si ay hadda ka dal dhex.

Waxay ku xiran tahay in xoogga dhererka kaari ah AB? Si loo xalliyo arrintan, waxaan qaadi doonaa oo silig of dhererka kala duwan ee haatan isku. cabir wuxuu inoo muujinaya in ciidamada oo duurka ku magnetic saamayn ku kaari hadda-sidday ah, waxay noqon doontaa si toos ah saamiyeed si ay dhererka kaari ee ku yaal beer magnetic.

Ha F - xoog, kaas oo u dhaqmo on kaari hadda-waday kaalinta duurka a magnetic, l - cimri kaari iyo I - dhexdeeda hadda.

Iyadoo isbedel ee l dhererka oo ka mid ah kaari iyo hadda waxa ku jira la beddelo, sida aan soo aragnay, iyo baaxadda ciidanka F.

ratio ee F xoog si dhererka waxaan kaari hadda oo madax bannaan si joogta ah haatan dhexdeeda; Sidaa darteed, ratio this sifaha karaan duurka ku magnetic.

tiro Tan waxaa lagu magacaabaa induction ku magnetic ama induction magnetic.

Yeero warqad induction B. ah magnetic Marka la qeexo, hal qori kartaa:

B = F / (I · l).

unit SI nidaamka induction magnetic qabata beerta induction taas oo kaari la hadda a of 1 A iyo 1 m dheer waxaa la hoos geliyey ciidan Name N. sida 1 unit: 1 Newton / (amper˖metr) (gaabiyaa 1 H / (AM)) .

Waxaan ku andacoodaan in H 1 / (AM) = 1 (V˖sek) / m²:

1 H / (AM) = 1 (nm) / (A˖m²) = 1 J / (A˖m²) = 1 (V˖A˖sek) / (A˖m²) = 1 (V s) / m².

Qaybta 1 volt-labaad yeedhay Weber (WB). Sidaas awgeed, 1 WB / m² ama 1 Tesla (T) - unit ka mid ah induction magnetic. Halka in nidaamka of unit emu cabbirka of induction magnetic - Gauss (G):

1 T = 10⁴ Gauss.

induction magnetic - tiro dulinka. jihada dulinka induction markan waa isbahaysi la jihada of khadadka xoog magnetic marayay marayso.

The SI ka daadanayo magnetic cufnaanta - sifo magnetic force field, la mid ah sida ay duurka ku korontada ku muujinayaa sifo awood duurka korontada.

Ogaanshaha beerta induction magnetic ah, waxaa suurtagal ah in loo xisaabiyo ciidanka on kaari hadda-sidday sida caanaha,

F = bi l.

In a kaari hadda-sidday eedeeyay ma aha oo kaliya guurto kala sooc lahayn in jiho oo kala duwan, laakiin sidoo kale jihada gaar ah. Mid kasta oo ka mas'uul ah waxay saamaysaa ciidanka magnetic in loo kala qaado si kaari ah. Wadarta ciidamada oo dhan ka mooshinka qasan yahay eber, iyo wadarta ciidamada dhaqdhaqaaqa si toos ah u yeedhay ciidanka Ampere.

Guud ahaan, xaddiga ciidan oo u dhaqmo on kaari hadda-sidday lagu meeleeyay beer magnetic xeer qeexo Ampere:

F = bi l α la ogeysiiyo dembigiisii α - xagal u dhexeeya jihada hadda (I) iyo dulinka field magnetic ah (B).

induction magnetic field waa tiro ahaan siman yihiin in ay ciidanka taas oo saameyn ku duurka ku magnetic halkii unit element hadda u amro dadab iyo in ay dulinka ee induction. induction magnetic ku salaysan guryaha warbaahinta.
