Thermoelectric Magnet
Designed for classroom demonstrations, this magnet consists of a heavy copper bar bent into a circle with a piece of dissimilar metal brazed across the extended arms. Attatched to each of these thermal junctions is a heavy copper plate extending downward. One plate is immersed in water and the other heated producing a magnet with a 400 lb pull.(1)
