Amandla kazibuthe phakathi kwezintambo ezimbili ezihambisanayo - izinkinga nezixazululo
1. Ama-conductor amabili ahambisanayo aphethe ama-current I 1 kanye no-I 2 , njengoba kuboniswe esithombeni esingezansi. Ubukhulu kanye nesiqondiso samandla kazibuthe atholwa yiwo womabili ama-conductor ? (μ o = 4π. 10 -7 Wb.A -1 .m -1 )
Kwaziwa:
The okwamanje kagesi 1 (I1) = 3 Ama-Ampere
Ugesi wamanje 2 (I 2 ) = 5 Ampere
Ukuvuleka kwesikhala esikhululekile (µo ) = 4π x 10 -7 wb A -1 m -1
Ibanga phakathi kwabaqhubi bobabili (L) = 5 cm = 5 x 10 -2 amamitha
Okufunwayo: Ubukhulu kanye nesiqondiso samandla kazibuthe
Isixazululo:
Isiqondiso samandla kagesi ku-conductor 1 siphambene nesiqondiso samandla kagesi ku-conductor 2. Ama-current aphikisanayo (ngakwezinye izindlela eziphambene) anamandla okuxoshana.

F/l = 6 x 10 -5 Newton
2. Izintambo ezimbili ezihambisanayo ezithwala imisinga I 1 kanye ne-I 2 ziqhelelene ngamasentimitha angu-20. Ubukhulu bamandla kazibuthe abonwa yintambo ngayinye (μ o = 4π. 10 -7 Wb.A -1 .m -1 )
Kwaziwa:
Ugesi wamanje 1 (I)1) = 5 Ama-Ampere
Ugesi wamanje 2 (I 2 ) = 4 Ampere
Ukuvuleka kwesikhala esikhululekile (µo ) = 4π x 10 -7 wb A -1 m -1
Ibanga phakathi kwezintambo zombili (L) = 20 cm = 20 x 10 -2 amamitha
Okufunwayo: Ubukhulu bamandla kazibuthe
Isixazululo:
Isiqondiso samandla kagesi ku-conductor 1 siphambene nesiqondiso samandla kagesi ku-conductor 2. Ama-current aphikisanayo (ngakwezinye izindlela eziphambene) anamandla okuxoshana.
Ubukhulu bamandla kazibuthe:
F/l = 2 x 10 -5 Newton
