B The Galvanometer's core

  1. Nov 21, 2017 #1
    There aren't any eddy currents in the metallic core of the galvanometer , Although it moves in a magnetic field? If it's right , why?

    Welcome to the PF. :smile:

    What reading have you done about eddy currents? What are the Relevant Equations?

    Thanks! ... Eddy currents are induced in a metal when it feels a changing magnetic field . Then its internal temperature gets high and startes to melt . we apply that to the induction furnace... That's all what I knew about them .
