-Thermoelectric magnet+Thermoelectric magnet, material properties of alloys create a potential difference and create a magnetic field using the Seebeck effect (described here [[https://​en.wikipedia.org/​wiki/​Thermoelectric_effect#​Seebeck_effect | Seebeck Effect]]).
  
  
  
-Heat one side of the thermocouple with the torch to get an electromagnet.  ​Updated on: 06/21/13 +Updated on Jan 7, 2020

 +Paraphrased:​ Suspend the magnet (the piece with the plates) from a lab stand. Immerse one copper plate in cold water and heat the other with a torch. Hold the other metal plate up flat against the magnet'​s surface, then release once it can hold itself up. You can try to hang masses from it, if the magnetic attraction is strong enough.
