Igitekerezo cy'amashanyarazi

Muri electroromagnesm, umubare w'amashanyarazi unyura mu gice icyo ari cyo cyose cyambukiranya umurongo kuri buri gihe cyitwa ubukana bwa none, cyangwa ubukungu gusa. Ikimenyetso kuri ubu ni njye, kandi igice ni ampare (a), cyangwa gusa "a marie Ampère, 17. Umuhanga mu bya fiziki hamwe na chimisi, ampere, yitiriwe izina rye).

Mu mashanyarazi, hateganijwe ko icyerekezo cy'ibishyinganiza ibirego byiza ari icyerekezo cy'ubu. Mubyongeyeho, mubuhanga, icyerekezo cyerekezo cyerekezo cyibiroga nabyo gikoreshwa nkicyerekezo cyubu. Ubunini bwibigezweho bugaragazwa na Qured Q Gutembera mu gice cyambukiranya umuyobora kuri buri gihe, cyitwa ubukana bwa none.
Hariho ubwoko bwinshi bwabatwara muri kamere itwara amashanyarazi. Kurugero: Electrons yimukanwa mubayobora, ion muri electrolytes, electron na ions mumikino ya plasma, kandi igahambo mumaguru. Urugendo rwabatwara rukora amashanyarazi.
