Question

Experiment 3a: Stand the metal pipe on end and drop the non-magnetic (or only slightly magnetic) cylinder through it. What happens? If you had to explain this and predict about how long the bar would take to reach the pipe’s lower end, how would you do that?

Experiment 3b: Now drop the magnetic (or more magnetic) cylinder through the metal pipe. What happens? Explain this behavior—use diagrams as necessary (probably very necessary). Is the difference in “fall time” because the magnet is somehow adhering to the metal (like a magnet adhering to a refrigerator)? How do you know?
