5E50.30 - Thermoelectric Magnet
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.
The following table gives the elements in the thermoelectric series in order:
