Hey,
I have one question about the eddy current brake, or electromagnetic induction at all. For instance, slowing a roller coaster from let me say 40m/s to 10m/s in 20m by a eddy current brake(THIS IS NO HOMEWORK!). What is about the conservation of energy in this case. can you say that E kin + Epot->E' kin + E' pot + E' therm or is this wrong? Is it valid to use the conservation of energy in this case at all? I am not sure! How do you think about this problem? I am not even sure, whether all the energy lost by the slowing down procedure goes into thermal energy?
sry about my english, but I do not live in a english-speaking country...
