Gold is a better electrical conductor than copper. How do you think the speed of the falling magnet through a gold tube would compare to the speed of the falling magnet through the copper tube? Refer back to the Lenz law demonstration.
Could you please explain me what's going on in this situation? |

The magnet should fall slower in the gold tube.
From wiki: The lower the resistivity of the material, the greater the size and effect of eddy currents. http://en.wikipedia.org/wiki/Eddy_current -------------------- "It's elementary, My Dear Quantum"...The Sherlock Holmes of physics.
