17.July.2024Thermoelectric. In 1821, German physicist Thomas Johann Seebeck observed that a nearby magnetic compass needle was deflected by a closed electrical circuit made of two different metals. Two years later, physicists Hans Christian Ørsted and Jean Baptiste Joseph reported that the interaction of the two metals, once connected in a circuit, had generated an electrical current because one was warmer than the other. Interestingly, Italian physicist Alessandro Volta—in whose honor the term volt is named—had observed and explained the same phenomenon in 1794 using nerves from a dead frog. Volta generated an electric current using a metal wire, two glasses of water (each at a different temperature) and the nerves of the frog as an electrical bridge. A grisly image, but one which foreshadowed future scientific breakthroughs.
