Ya know, I do! The magnet going throuhg the pipe is like a magnet going into tons of little tiny rings which induce a current to resist the change. So, the magnet's weight has to overcome the force created by the ring's induced current (FBI law) so it goes slower than a steel ball which just has weight and induces no current. Help at all? Yes, i am a nerd. Won't deny it
