Ma conductor awiri ofanana omwe amanyamula mafunde - mavuto ndi mayankho

1. Waya P wonyamula mphamvu yamagetsi 6-A mmwamba monga momwe zasonyezedwera pachithunzi chili pansipa. Ngati µ _o = 4π.10 ^-7 wb A ^-1 m ^-1 ndipo pali mphamvu yobwezera pakati pa waya P ndi Q 1.2.10 ^-5 Nm ^– 1. Dziwani kukula ndi komwe magetsi amagetsi amachokera pa waya Q.

Zodziwika:

IP ₌ 6 Ampere

µ _o = 4π x 10 ^-7 wb A ^-1 m ^-1

F/l = 1,2 x 10 ^-5 N m ^-1

L = mita imodzi

Kufunidwa: Kukula ndi komwe magetsi amagetsi akupita pa waya Q

Yankho:

Kuwongolera kwa magetsi pa waya Q:

Pali mphamvu yoyipa pakati pa waya P ndi Q kotero kuti magetsi amagetsi pa waya P ali ndi mbali yosiyana ndi magetsi amagetsi pa waya Q.

Pa waya P, magetsi amakwera mmwamba kotero kuti pa waya Q magetsi amatsika.

Mphamvu yamagetsi pa waya Q:

2. Mawaya awiri ofanana, L, ndi M ali 2-cm kutali (onani chithunzi). Waya M imanyamula magetsi a 4-A. Mawaya onsewa ali ndi mphamvu yotsutsana 6 x 10 ^-5 Nm ^-1 . Dziwani kukula ndi komwe magetsi amagetsi akupita pa waya L. (µ _o = 4π.10 ^-7 Wb.A ^-1 m ^-1 )

Zodziwika:

IM ₌ 4 Ampere

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

Kufunidwa: Kukula ndi komwe magetsi amagetsi akupita pa waya L

Yankho:

Kuwongolera kwa magetsi pa waya L:

Apa pali mphamvu yoyipa pakati pa waya L ndi waya M kotero kuti magetsi pa waya L ali mbali yosiyana ndi magetsi pa waya M.

Pa waya M, magetsi amayendetsedwa mmwamba kotero kuti pa waya L magetsi amatsika.

Mphamvu yamagetsi pa waya L:

3. Waya P ndi Q ali mtunda wa mita imodzi. Waya P wonyamula magetsi 1-A. Ngati µo ₌ 4 π.10 ^-7 Wb.A ^-1 .m ^-1 ndipo pali mphamvu yokoka pa wina ndi mnzake 10 ^-7 Nm ^-1 , dziwani kukula ndi komwe magetsi amagetsi akuyendera pa waya Q.

Zodziwika:

I_P = 1 Ampere

µ _o = 4π x 10 ^-7 wb A ^-1 m ^-1

F/l = 10 ^-7 N m ^-1

L = mita imodzi

Kufunidwa: Kukula ndi komwe magetsi amachokera pa waya Q

Yankho:

Kuwongolera kwa magetsi pa waya Q:

Apa pali mphamvu yokopa pakati pa waya P ndi waya Q kotero kuti njira ya magetsi pa waya P ndi yofanana ndi njira ya magetsi pa waya Q.

Pa waya P, njira ya magetsi imakhala pansi kotero kuti pa waya Q njira ya magetsi imakhala pansi.

Mphamvu yamagetsi pa waya Q:
