Amperium,[1] signo A,[2] saepe amp imminutum,[3] est unitas basalis SI fluxus oneris electrici,[4][5][6] ex Andrea Maria Ampère appellata, mathematico et physico Francico, qui pater electromagntismi cum Ioanne Christiano Ørsted physico Danico aestimatur.
Definitio mathematica
[recensere | fontem recensere]Amperium anno 1948 sic definitum est, postulando constantem magneticum in lege Biot-Savartiana:
- .
Fluxus electricus constans fit si in duobus conductoribus parallelis contineatur, longitudinibus infinitis, quorum diametram neglegere possumus, uno metro subtiliter inter eos, vim in quoque conductore creat magnitudinis 2×10–7 Newtonii per metrum conductoris.
