1. Laba fiilo oo dheer oo is barbar socda oo sita hirar isku mid ah, 3-A. Haddii masaafada u dhaxaysa labada fiilo ay tahay 40 cm, go'aami goobta birlabta ee barta P. μ o = 4 π x 10 −7 Wb A −1 m −1.
La yaqaan:
Koronto (I) = 3-A
Masaafada u dhaxaysa siligga 1 iyo 2 (r 12 ) = 40 cm = 0.4 m
Masaafada u dhaxaysa siligga 1 iyo P (r 1P ) = 30 cm = 0.3 m
Masaafada u dhaxaysa siligga 2 iyo P (r 2P ) = 40 – 30 = 10 cm = 0.1 m
µo = 4π x 10-7 Wb.A-1.m-1
La doonayo: Goobta birlabta ee barta P
Xalka:
Goob birlab ah oo ay soo saartay silig 1 (bidix) :
Goob birlab ah oo ay soo saartay silig 2 (midig) :
Goobta birlabta ee barta P:
BP =B2 - B1 = 6x10-6 - 2 x 10-6
BP = 4x10-6 Tesla
2. Silig dheer oo sidda koronto 2-A. Go'aami baaxadda iyo jihada goobta birlabta ee barta P. (μ)o = 4π x 10-7 Wb A-1 m-1)
La yaqaan:
Koronto (I) = 2 A
Masaafada u dhaxaysa siligga iyo barta P (r)P) = 4 cm = 0.04 m
μo = 4π x 10-7 Wb. A-1 m-1
La doonayo: Weynaanta iyo jihada soo-kicinta birlabta ee barta P
