Electro-dynamic. adj.
The opposite of electrostatic; a qualification of phenomena due to
current electricity.
Synonym--Electro-kinetic.
Electro-dynamic Attraction and Repulsion.
The mutual attraction and repulsion exercised by currents of electricity
upon each other. The theory of the cause is based upon stress of the
luminiferous ether and upon the reaction of lines of force upon each
other. For a resumé of the theory see Induction, Electro-magnetic.
Electro-dynamics.
The laws of electricity in a state of motion; the inter-reaction of
electric currents. It is distinguished from electro-magnetic induction
as the latter refers to the production of currents by induction. The
general laws of electro-dynamics are stated under Induction,
Electro-magnetic, q. v.
Synonym--Electro-kinetics.
