Chii chinokanganisa magnitude e magnetic induction pa wire conductor.
mhinduro
Dzidza nzira yemagnetic induction uye tsananguro yapfuura.
3. Mwenje wemagetsi I unoyerera pawaya yemuchina wekufambisa magetsi. Chii chinonzi magnetic induction iri pakati pedenderedzwa (P)? (µ o = 4π.10 -7 Wb.m -1 .A -1 )
Zvinozivikanwa:
Nharaunda yedenderedzwa (r) = 6 cm = 6 x 10-2 mamita
Mwenje wemagetsi (I) = 8 Ampere
Kupinda kwemuchina wevacuum (µo ) = 4π x 10 -7 Wb.A -1 m -1
Zvinodiwa: magnetic induction iri pakati pedenderedzwa (P)
Solution:
360 o – 90 o = 270 o . 270 o / 360 o = 3/4 wobva waita 270 o = 3/4 denderedzwa
Fomura yemagineti iri pakati pe coil ine zvishwe zvakati wandei:
B = simba remagineti, N = nhamba yemawindings, I = magetsi emagetsi, r = radius yekukombama
Mudambudziko riri pamusoro apa, pane kutenderera kumwe chete kuitira kuti N ibviswe mu equation. Wire coil iri pamusoro apa haisi denderedzwa rimwe chete asi denderedzwa re 3/4. Fomura iri pamusoro inogadziriswa zvakare nedambudziko iri:
Kupinza kwemagineti pakati pedenderedzwa:
4. Current 2 A inoyerera pawaya yakatenderera semufananidzo. Ndeipi hukuru uye gwara re magnetic induction panzvimbo P kana radius yedenderedzwa iri 4π cm.
Zvinozivikanwa:
Nharaunda (r) = 4π cm = 4π x 10-2 mamita
Mwenje wemagetsi (I) = 2 Ampere
Kupinda kwemuchina wevacuum (µo ) = 4π x 10 -7 Wb.A -1 m -1
Zvinodiwa: Hukuru uye gwara re magnetic induction panzvimbo P
Solution:
Coil yewaya iri padambudziko rataurwa pamusoro apa ine 1/2 denderedzwa.
Hukuru hwe magnetic induction panzvimbo P:
