The generation of an electric current (or electromotive force) when two
conductors of different metals are joined at their ends to form a circuit,
with the two junctions kept at different temperatures. The Seebeck effect
is the basic operating principle of the thermocouple.
It is named after the German physicist Thomas Seebeck (1770–1831)
who discovered it in 1821. See also Peltier
effect.
