Ama-conductor amabili ahambisanayo aphethe ama-current - izinkinga nezixazululo

1. Intambo P ethwala ugesi ongu-6-A phezulu njengoba kuboniswe esithombeni esingezansi. Uma µ _o = 4π.10 ^-7 wb A ^-1 m ^-1 futhi kukhona amandla okuxosha phakathi kwentambo P no-Q 1.2.10 ^-5 Nm ^– 1. Nquma ubukhulu kanye nesiqondiso sogesi kuntambo Q.

Kwaziwa:

I-IP ₌ ama-Ampere angu-6

µ _o = 4π x 10 ^-7 wb A ^-1 m ^-1

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

L = 1 imitha

Okufunayo: Ubukhulu kanye nesiqondiso samandla kagesi ku-wire Q

Isixazululo:

Isiqondiso samandla kagesi ku-wire Q:

Kukhona amandla okuxosha phakathi kwentambo P ne-Q ukuze ugesi okwintambo P ube nohlangothi oluphambene nogesi okwintambo Q.

Ku-wire P, ugesi uphezulu ukuze ugesi ku-wire Q uphansi.

Ugesi ocingweni Q:

2. Izintambo ezimbili ezihambisanayo, u-L, no-M ziqhelelene ngamasentimitha angu-2 (bheka isithombe). Intambo u-M uphethe ugesi ongu-4-A. Zombili izintambo zinamandla okuxoshana 6 x 10^-5 Nm^-1Thola ubukhulu kanye nesiqondiso samandla kagesi ku-L. (µ)_o = 4π.10^-7 I-Wb.A^-1m^-1)

Kwaziwa:

I_M = Ama-Ampere ama-4

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

Okufunayo: Ubukhulu kanye nesiqondiso samandla kagesi ku-L

Isixazululo:

Isiqondiso samandla kagesi ku-wire L:

Tnansi amandla axoshayo phakathi kwentambo L kanye nentambo M ukuze ugesi okwintambo L ube sendleleni ephambene nogesi okwintambo M.

Ku-wire M, ugesi uqondiswa phezulu ukuze ku-wire L ugesi ubheke phansi.

Ugesi ocingweni L:

3. Intambo P kanye ne-Q ziqhelelene nge-1-m. Intambo P ephethe amandla kagesi angu-1-A. Uma µ_o = 4π.10^-7 I-Wb.A^-1.m^-1 futhi kukhona amandla akhangayo komunye nomunye 10^-7 I-Nm^-1, thola ubukhulu kanye nesiqondiso samandla kagesi ku-wire Q.

Kwaziwa:

I_P = Ama-Ampere ama-1

µ _o = 4π x 10 ^-7 wb A ^-1 m ^-1

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

L = 1 imitha

Okufunayo: Ubukhulu kanye nesiqondiso samandla kagesi ku-Q

Isixazululo:

Isiqondiso samandla kagesi ku-wire Q:

Tnansi amandla akhangayo phakathi kwentambo P kanye nentambo Q ukuze isiqondiso samandla kagesi kuntambo P sifane nesiqondiso samandla kagesi kuntambo Q.

Ku-wire P isiqondiso samandla kagesi siyehla ukuze ku-wire Q isiqondiso samandla kagesi siyehla.

Ugesi ocingweni Q:
