Garoon birlab ah oo ku yaal bartamaha qaansada hadda jirta - dhibaatooyinka iyo xalalka

1. Iyada oo ku saleysan sawirka hoose, haddii gacanka qalooca siligga uu yahay 50 cm, go'aami baaxadda goobta birlabta ee bartamaha qalooca (barta 0, fiiri sawirka hoose). (µ _o = 4π.10 ^-7 Wb.A ^-1 m ^-1 )

La yaqaan:

Gacanka (r) = 50 cm = 0.5 m

Koronto (I) = 1.5 Ampere

Rugista faakuumka (µ _o ) = 4π.10 ^-7 Wb.A ^-1 m ^-1

La Doonayo: Cabbirka goobta birlabta

Xalka:

360 ^o = 1 wareeg oo goobaaban ah . 120 ^o / 360 ^o = 1/3 ka dibna 120 ^o = 1/3 x wareeg oo goobaaban ah.

Isle'egta goobta birlabta ee bartamaha gariiradda oo leh dhowr wareeg:

B = baaxadda goobta birlabta, N = tirada wareegyada, I = hadda korantada, r = gacanka qalooca

Dhibaatada kor ku xusan, waxaa jira hal wareeg oo keliya si N looga saaro isle'egta. Xidhmada siligga ee dhibaatada kor ku xusan maaha 1 goobood laakiin waa 1/3 goobood:

Baaxadda goobta birlabta ee bartamaha qalooca:

2. Iyada oo ku saleysan sawirka hoose, qulqulka korantada ee fiilada waa 6-A iyo gacanka qalooca waa R = 3π cm, si loo go'aamiyo baaxadda goobta birlabta ee barta P.

La yaqaan:

Gacanka qalooca (r) = 3π cm = (3π/100) m

= 3π/10 ² m = 3π.10 ^-2 m

Koronto (I) = 6 A

Rugista faakuumka (µ _o ) = 4π.10 ^-7 Wb.A ^-1 m ^-1

La Doonayo: Cabbirka goobta birlabta

Xalka:

360^o = 1 goobada goobaabin. 45^o / 360^o = 1/8 ka dibna 45^o = 1 / 8 x goobada goobaabin.

Baaxadda goobta birlabta ee bartamaha qalooca:

3. Qulqulka korantada ee fiilada = 9-A, gacanka qalooca (R) = 2π cm iyo µ _o = 4π.10 ^-7 Wb.A ^-1 .m ^-1 , waxay go'aamisaa baaxadda goobta birlabta ee barta P.

La yaqaan:

Gacanka qalooca (r) = 2π cm = (2π/100) m

= 2π/10 ² m = 2π.10 ^-2 m

Koronto (I) = 9 A

Rugista faakuumka (µ _o ) = 4π.10 ^-7 Wb.A ^-1 m ^-1

La Doonayo: Cabbirka goobta birlabta ee barta P

Xalka:

360^o - 120^o = 240^o. 240^o / 360^o = 2/3 ka dibna 240^o = 2/3 x goobada goobaabin.
