Condition :   Good   
Principle :   Thermocouple and Electromagnets
Area of Study :  Thermoelectricity
Equipment :   Thermoelectric loop, electromagnet iron core with plate, liquid nitrogen, Bunsen burner or propane torch, masses.
Procedure :   Secure the loop into the iron core with the set screws.  Place one end of the loop into liquid nitrogen for a few minutes.  Then, heat the other end with the propane torch.  After several minutes the electromagnet should be working well enough to  attach the plate and then hang a 1 kg mass off of it.
