Relating to the movement of electric charges and the forces they create.
The electrodynamic properties of the material were studied in the laboratory.
Electrodynamic → It is formed from "electro-" (from Greek "ēlektron", meaning amber or electricity) and "dynamic" (from Greek "dynamis", meaning power or force). The word refers to the power or force associated with electric charges in motion.
Think of 'electricity' ('electro-') and 'power' ('dynamic') working together — that's what electrodynamic means.
