Koronto

Ka Wikipedia
U bood: gooshitaan, raadi

La'aan Electric ugu dambeyntii waa qurubyada hoose ee feature aasaasiga ah oo la xiriira in ay kala duwan oo cajiib ah u wada socdaan electromagnetic. Waxaa jira laba masuul korontada soo horjeeda, wanaagsan iyo mid xun. Brand ayaa isku mid ah oo mudadan in midba midka kale isaga ka riixdo, calaamadaha kala duwan oo midba midka kale soo jiitaan. Sharciga Coulomb, ciidamada waa si toos ah saamiyo si ay u aqbasho labada eedeeyey iyo dhigmayn inay square ee masaafada u dhexaysa. Hadda Electric waxa ku wareegsan garoonka koronto, in motion, marka laga soo tago beerta ku magnetic xiligaas dadkaasi. Beeraha, waxay tilmaamayaan isla'egyada Maxwell ayaa muujinaya korontada iyo magnetism dhexeeya xiriir ah.

Protons on aasaasiga ah ee qurubyada yahay, la'aan xun ee electrons. Nuclei waa protons, electrons ee xudunta u egna. Sida caadiga ah la egna ay leedahay electrons badan intii protons, sidaa awgeed, waa in koronto dhex-dhexaad ah oo dhan, laakiin sidoo kale electrons ka guurto karaa in la egna kale in la soo saaro udhigo koronto eedeeyay. Qaar badan oo ka mid ah cunnooyinka adkaha ah waxay ka kooban yihiin udhigo, sida xafiisyada neerfaha.

Guud ahaan, heesaha macroscopic leedahay koronto wanaagsan iyo mid xun sida badan. Xaaladaha qaarkood, tusaale ahaan, laba xabbadood oo miyirsiin ka dhan ah midba midka kale, electrons ama udhigo guuri karaan qaybta kale, si ay labadaba waa loo siman yahay, laakiin la'aan korontada ka soo horjeeda, ama danab ahbaa.
