Named after John Henry Poynting (1852–1914), English physicist.
APAKAH MAKSUD POYNTING THEOREM dalam CORSICA?
Teorem Poynting
Dalam elektrodinamika, teorem Poynting adalah pernyataan pemuliharaan tenaga untuk medan elektromagnetik, dalam bentuk persamaan pembezaan separa, disebabkan oleh ahli fizik British John Henry Poynting. Teorem Poynting adalah analogi dengan teorem tenaga kerja dalam mekanik klasik, dan secara matematik sama dengan persamaan kesinambungan, kerana ia mengaitkan tenaga yang disimpan dalam medan elektromagnetik untuk kerja yang dilakukan pada pengagihan caj, melalui aliran tenaga.
Definisi Poynting theorem dalam kamus Corsica
Takrif teorem Poynting dalam kamus adalah teorem bahawa kadar aliran tenaga elektromagnet melalui kawasan unit adalah sama dengan vektor Poynting, iaitu produk salib intensiti medan magnet dan magnet.
