1. Ho latela setshwantsho se ka tlase, haeba radius ya kobeho ya terata e le 50 cm, fumana boholo ba matla a makenete bohareng ba kobeho (ntlheng ya 0, bona setshwantsho se ka tlase). (µ o = 4π.10 -7 Wb.A -1 m -1 )
Tse tsejoang:
Radius (r) = 50 cm = 0.5 m
Motlakase oa motlakase (I) = 1.5 Ampere
Ho kenella ha vacuum (µo ) = 4π.10 -7 Wb.A -1 m -1
Ho batloa: Boholo ba matla a makenete
Tharollo:
360 o = Selikalikoe se le seng sa selikalikoe . 120 o / 360 o = 1/3 ebe 120 o = 1/3 x Selikalikoe sa selikalikoe.
Tekanyo ea matla a makenete bohareng ba koili ka li-loop tse 'maloa:
B = boholo ba matla a makenete, N = palo ea li-loop, I = motlakase oa motlakase, r = radius ea kobeho
Bothateng bo ka hodimo, ho na le sekotwana se le seng feela e le hore N e tloswe ho equation. Khoele ya terata bothateng bo ka hodimo ha se sedikadikwe se le seng empa ke sedikadikwe sa 1/3:
Boholo ba matla a makenete bohareng ba kobeho:
2. Ho latela setshwantsho se ka tlase, phallo ya motlakase ka hara terata ke 6-A mme radius ya kobeho ke R = 3π cm, ho fumana boholo ba matla a makenete ntlheng ya P.
Tse tsejoang:
Radius ea kobeho (r) = 3π cm = (3π/100) m
= 3π/10 2 m = 3π.10 -2 m
Motlakase (I) = 6 A
Ho kenella ha vacuum (µo ) = 4π.10 -7 Wb.A -1 m -1
Ho batloa: Boholo ba matla a makenete
Tharollo:
360o = 1 sekhetho ea selikalikoe. 45o / 360o = 1/8 ebe 45o = 1 / 8 x sekhetho ea selikalikoe.
Boholo ba matla a makenete bohareng ba kobeho:
3. Phallo ea motlakase ka terata = 9-A, radius ea kobeho (R) = 2π cm le µ o = 4π.10 -7 Wb.A -1 .m -1 , e fumana boholo ba matla a makenete ntlheng ea P.
Tse tsejoang:
Radius ea kobeho (r) = 2π cm = (2π/100) m
= 2π/10 2 m = 2π.10 -2 m
Motlakase (I) = 9 A
Ho kenella ha vacuum (µo ) = 4π.10 -7 Wb.A -1 m -1
Ho batloa: Boholo ba matla a makenete ntlheng ea P
Tharollo:
360o - 120o = 240o. 240o / 360o = 2/3 ebe 240o = 2/3 x sekhetho ea selikalikoe.
Boholo ba matla a makenete bohareng ba kobeho:
