1. Zvichibva pamufananidzo uri pazasi, kana radius yekukombama kwewaya iri 50 cm, sarudza kukura kwesimba remagineti pakati pekukombama (panzvimbo 0, ona mufananidzo uri pazasi). (µ o = 4π.10 -7 Wb.A -1 m -1 )
Zvinozivikanwa:
Nharaunda (r) = 50 cm = 0.5 m
Mwenje wemagetsi (I) = 1.5 Ampere
Kubvumidzwa kwevacuum (µo ) = 4π.10 -7 Wb.A -1 m -1
Zvinodiwa: Hukuru hwesimba remagineti
Solution:
360 o = denderedzwa rimwe chete redenderedzwa . 120 o / 360 o = 1/3 wozoti 120 o = 1/3 x denderedzwa redenderedzwa.
Kuenzanisa kwesimba remagineti pakati pe coil nemaropu akati wandei:
B = hukuru hwesimba remagineti, N = nhamba yezvirukwa, I = magetsi emagetsi, r = nharaunda yekukombama
Mudambudziko riri pamusoro apa, pane loop imwe chete kuitira kuti N ibviswe mu equation. Wire coil iri pamusoro apa haisi denderedzwa rimwe chete asi denderedzwa re 1/3:
Kukura kwesimba remagineti pakati pekukombama:
2. Zvichibva pamufananidzo uri pazasi, magetsi anoyerera muwaya i6-A uye radius yekukombama iR = 3π cm, kuti uone hukuru hwesimba remagineti panzvimbo P.
Zvinozivikanwa:
Nharaunda yekukombama (r) = 3π cm = (3π/100) m
= 3π/10 2 m = 3π.10 -2 m
Mwenje wemagetsi (I) = 6 A
Kubvumidzwa kwevacuum (µo ) = 4π.10 -7 Wb.A -1 m -1
Zvinodiwa: Hukuru hwesimba remagineti
Solution:
360o = 1 circumference yedenderedzwa. 45o / 360o = 1/8 zvino 45o = 1 / 8 x circumference yedenderedzwa.
Kukura kwesimba remagineti pakati pekukombama:
3. Kuyerera kwemagetsi muwaya = 9-A, radius yekukombama (R) = 2π cm uye µ o = 4π.10 -7 Wb.A -1 .m -1 , inoona hukuru hwesimba remagineti panzvimbo P.
Zvinozivikanwa:
Nharaunda yekukombama (r) = 2π cm = (2π/100) m
= 2π/10 2 m = 2π.10 -2 m
Mwenje wemagetsi (I) = 9 A
Kubvumidzwa kwevacuum (µo ) = 4π.10 -7 Wb.A -1 m -1
Zvinodiwa: Hukuru hwesimba remagineti panzvimbo P
Solution:
360o - 120o = 240o. 240o / 360o = 2/3 zvino 240o = 2/3 x circumference yedenderedzwa.
Kukura kwesimba remagineti pakati pekukombama:
