The Thermoelectricity Demo is an excellent way to illustrate the Seebeck Effect. When a thermoelectric loop is fashioned from two dissimilar metals and they are connected together at two junctions, and a temperature gradient exists, a voltage or electromotive force (EMF) is induced which is enough to deflect a magnetic compass. Our device features an aluminum strip on the bottom with a bent copper strip on top. There is a depression underneath the copper loop for placement of a small magnetic compass. Also, our device features an attached handle for safety and ease of use.
