Thanks guys. From doing a little bit of lab testing and pondering, I gather that dropping a magnet down a conductive pipe produces lots of drag due to the Eddy currents forming inside the pipe. The same magnet falling down a coil experiences little drag and the drag force is probably...

What is the drag force on a magnet falling through a coil? I have found several sources online describing the drag force on a magnet falling through a conductive pipe. How might this vary if a coil is used in place of a pipe? Does the coil need to be connected to a circuit to create this force?
