Kev txhais ntawm electromagnetic teb
Electromagnetic teb yog ib lo lus dav dav rau kev sib koom ua ke ntawm qhov nruab nrab sab hauv thiab sib zog thiab hluav taws xob sib nqus. Ib lub sijhawm ntsuas hluav taws xob ua teb tsim hluav taws xob, thiab lub sijhawm sib nqus tau tsim ib thaj chaw hluav taws xob. Qhov ob yog causal rau lwm tus thiab tsim daim teb hluav taws xob. Cov xov hluav taws xob muaj peev xwm tshwm sim los ntawm kev them cov xaim hluav taws xob txav ntawm cov ntsuas hluav taws xob hloov lossis los ntawm cov dej tam sim no nrog rau kev sib txawv. Txawm hais tias ua li cas los xij, xaim hluav taws xob nyob ib puag ncig tawm ntawm qhov nrawm nrawm nrawm los ua hluav taws xob electromagnetic. Lub tshuab hluav taws xob yog qhov nruab nrab ntawm kev siv hluav taws xob, nrog lub zog thiab kev nrawm, yog ib hom kev muaj ntawm cov khoom. Qhov xwm thiab cov yam ntxwv ntawm electromagnetic teb thiab cov cai ntawm lawv cov kev txav yog txiav txim siab los ntawm Maxwell' s sib npaug.
