Umthetho ka-Ampere

Usosayensi waseFrance u-Andre Marie Ampère (1775–1836) waphakamisa ubudlelwano obujwayelekile phakathi kwamandla kagesi ageleza kunoma yimuphi umqhubi kanye nensimu yamagnetic ekhiqizwa nxazonke zawo. Lona uMthetho ka-Ampère. Isibalo esingezansi siveza umthetho ka-Ampère.

—–> Umthetho ka-Ampere

Isamba sezingxenye (Σ) zensimu kazibuthe (B) esihambisana nobude beyunithi yomqhubi, siphindaphinda ubude beyunithi yomqhubi (∆l), silingana nomkhiqizo we-µo ₍ µo ₌ 4π x 10 ^-7 Tm/A) kanye nogesi (I).

Amandla kazibuthe aphakathi kwezintambo ezimbili eziqondile ezihambisanayo ezithwala ugesi

Ugesi ogeleza ngentambo udala insimu yamagnetic ezungezile. Uma intambo iqondile, imigqa yamagnetic field yakha indilinga, intambo eqondile ibe maphakathi nendilinga.

Uma kunezintambo ezimbili zokuqhuba eziqondile ezihambisanayo futhi zihlukaniswe yibanga elingu-L, khona-ke insimu yamagnetic edalwe ugesi kuntambo yokuqhuba 1 izwakala kuntambo yokuqhuba 2, ngokufanayo insimu yamagnetic edalwe ugesi kuntambo yokuqhuba 2 izwakala kuntambo yokuqhuba 1.

Isihloko Amandla kagesi, ishaja kagesi, insimu yamagnetic, amandla odonsa amadodaChaza ukuthi ugesi ungakhiqiza insimu yamagnetic. Uma ugesi ugeleza ngentambo ende kakhulu, eqondile, kukhiqizwa insimu yamagnetic, enemigqa yamagnetic field eyakha indilinga ezungeze intambo njengesikhungo.

Izinto eziphathelene nogesi, ishaja kagesi, insimu yamagnetic, amandla kazibuthe

Ngo-1819, usosayensi waseDenmark ogama lakhe linguHans Christian Oersted (1777–1851) wathola ubudlelwano phakathi kwemagnetism kanye nogesi , noma amashaja ahambayo . Wathola ukuthi lapho inalithi yekhampasi iseduze nocingo oluphethe ugesi, yayiphambuka. Lapho kungekho ugesi, inalithi yekhampasi yayikhomba enyakatho.

Inaliti yekhampasi iyimagnethi, ngakho amandla kazibuthe angayihambisa . Amandla kazibuthe (F) avelaphi? Eduze kwenaliti yekhampasi kukhona ucingo oluphethe ugesi, ngakho ugesi kumele ukhiqize amandla kazibuthe.

Bheka isithombe ngakwesokudla. Sebenzisa umthetho wesandla sokudla ukuze uthole isiqondiso samandla kagesi kanye nesiqondiso sensimu yamagnetic. Uma amandla kagesi (I) enyukela phezulu, isiqondiso sensimu yamagnetic (B) sizoba njengoba kuboniswe esithombeni ngakwesokunxele. Ngokuphambene nalokho, uma amandla kagesi ehla, isiqondiso sensimu yamagnetic sizoba njengoba kuboniswe esithombeni ngakwesokudla.
