Making/Inducing/Forming a current

  1. Feb 22, 2009 #1
    Is it possible to induce a current with just heating?
    i.e. if we have metal rods (conducting/non-conducting rods) and a heat source, can we make current and determine the direction and amount of current (if possible in relation to the heat energy)?
