1. Hlau P nqa tam sim no 6-A mus rau sab saud raws li qhia hauv daim duab hauv qab no. Yog tias µo = 4π.10 -7 wb A -1 m -1 thiab muaj lub zog rov qab ntawm hlau P thiab Q 1.2.10 -5 Nm – 1. Txheeb xyuas qhov loj thiab kev coj ntawm tam sim no ntawm hlau Q.
Paub:
IP = 6 Amperes
µ o = 4π x 10 -7 wb A -1 m -1
F/l = 1,2 x 10 -5 N m -1
L = 1 'meter'
Xav tau: Qhov loj thiab kev coj ntawm tam sim no ntawm xaim Q
Tshuaj:
Kev taw qhia ntawm hluav taws xob tam sim no ntawm xaim Q:
Muaj ib lub zog repulsive ntawm cov hlau P thiab Q yog li ntawd cov hluav taws xob ntawm cov hlau P muaj qhov kev taw qhia sib txawv rau cov hluav taws xob ntawm cov hlau Q.
Ntawm cov xov hlau P, cov hluav taws xob tam sim no nce mus rau sab saud yog li ntawm cov xov hlau Q cov hluav taws xob tam sim no nqis mus rau hauv qab.
Lub zog hluav taws xob ntawm cov hlau Q:
2. Ob txoj hlua hluav taws xob sib luag, L, thiab M sib nrug 2-cm (saib daim duab). Txoj hlua M nqa hluav taws xob ntawm 4-A. Ob txoj hlua hluav taws xob muaj lub zog rov qab rau ib leeg 6 x 10 -5 Nm -1 . Txheeb xyuas qhov loj thiab kev coj ntawm hluav taws xob ntawm txoj hlua L. (µo = 4π.10 -7 Wb.A -1 m -1 )
Paub:
IM = 4 Amperes
µ o = 4π x 10 -7 wb A -1 m -1
F/l = 6 x 10 -5 N m -1
L = 2 cm = 0.02 m
Xav tau: Qhov loj thiab kev coj ntawm tam sim no ntawm xaim L
Tshuaj:
Kev taw qhia ntawm lub zog hluav taws xob ntawm xaim L:
T yog lub zog rov qab ntawm cov hlau L thiab cov hlau M kom cov hluav taws xob ntawm cov hlau L nyob rau hauv qhov kev taw qhia rov qab rau cov hluav taws xob ntawm cov hlau M.
Ntawm cov xov hlau M, cov hluav taws xob raug coj mus rau sab saud kom ntawm cov xov hlau L, cov hluav taws xob raug coj mus rau hauv qab.
Lub zog hluav taws xob ntawm cov hlau L:
3. Cov xov hlau P thiab Q nyob sib nrug 1-m. Cov xov hlau P nqa tam sim no 1-A. Yog tias µo = 4 π.10 -7 Wb.A -1 .m -1 thiab muaj lub zog nyiam rau ib leeg 10 -7 Nm -1 , txiav txim siab qhov loj thiab kev coj ntawm tam sim no ntawm cov xov hlau Q.
Paub:
IP = 1 Amperes
µ o = 4π x 10 -7 wb A -1 m -1
F/l = 10 -7 N m -1
L = 1 'meter'
Xav tau: Qhov loj thiab kev coj ntawm tam sim no ntawm xaim Q
Tshuaj:
Kev taw qhia ntawm hluav taws xob tam sim no ntawm xaim Q:
Nov yog lub zog nyiam ntawm cov hlau P thiab cov hlau Q yog li ntawd qhov kev taw qhia ntawm cov hluav taws xob tam sim no ntawm cov hlau P yog tib yam li qhov kev taw qhia ntawm cov hluav taws xob ntawm cov hlau Q.
Ntawm xov hlau P qhov kev taw qhia ntawm cov hluav taws xob yog downward yog li ntawm xov hlau Q qhov kev taw qhia ntawm cov hluav taws xob yog downward.
Lub zog hluav taws xob ntawm cov hlau Q:
