Problem 14. A permanent magnet falling through a conducting (but nonmagnetic, e.g. aluminum) pipe reaches a fairly low terminal velocity, while the same magnet falling through a nonconducting (e.g. plastic) pipe of the same dimensions falls freely with a downward acceleration of g. Explain in words what is happening in the conducting pipe that creates an upward force on the magnet. Include a sketch of any relevant fields/currents/etc.-and their directions! as part of your answer.
